What are some things to replace when a car hesitates at low rpms?
First off figure out and diagnose why its doing that, or else you wont have a clue what it is or else youre going to just be throwing parts at it and money down the drain by just simply guessing. From my experience its not one cut and dry answer It could be lots of things. Most likely if it has a carburetor the carburetor needs an adjustment, or spark plugs are old and worn out, air filter is possibly worn out and clogged with debris so its restricting the airflow. Oxygen sensor is a possibility. Or it could be a fuel filter/injector clogged/ fuel pump blocking proper fuel flow. The catalytic converter or exhaust could be clogged up with carbon deposits, but i doubt that. Lastly if its really high mileage like 200,000–400,000 miles and it could just simply be old and worn out and the piston rings arent sealing very well, so its low on compression which will make most engines low on power but thats pretty unlikely especially if youve taken good care of it, done oil changes on time and its maintained. All these items are consumables, they are regular car maintenance repairs. Its amazing how much better a car will run when you replace all those things and wear out over time. Take it to a reputable ase certified mechanic or if the car is under warranty go to the dealer. Or if you got a buddy thats good with cars take it to him. The good news is its usually something simple, and all those things arent hard to fix unless its the fuel filter/fuel pump. tell me how it goes. Good luck dude!
Does a faulty knock sensor affect engine performance?
Yes, it absolutely can.As someone else mentioned, the majority of failures are due to the lack of a signal. Performance is unaffected if there's no signal. However, OEMs can decide to force a "limp mode" condition to protect the engine which will be a significant and obvious reduction in power.If you have an over-active knock sensor then engine performance will be affected. For most vehicles, the reduction in power is probably going to be small. However, for high-performance engines, especially turbocharged or supercharged motors, the power loss will be more noticeable.If the knock sensor were to consistantly report knock then most modern ECUs react by pulling a large amount of ignition timing (5+ degrees of retard) which can reduce engine output by up to 25%.The ECU will also start to learn knock events. If the knock occurs several times at the same conditions (load) the modern ECU responds by applying a small reduction in timing at that point in the ignition trim table. This means that the engine's performance will degrade over time if the knock sensor continues to report false knock.You can reset the corrections by resetting the ECU. The easiest way to do that is to unplug the battery for a while. The ECU will then use the base ignition values, returning any lost engine power due to the learning. This is important to do when you replace a faulty knock-sensor.Also follow me on … Instagram — Come and Drive It (@comeanddriveit) Facebook — Come and Drive ItTwitter — Come and Drive It
Why could my Toyota Corolla lose power when going up a steep hill?
Clogged fuel filterWhen you put your foot down on the accelerator and don’t get the reaction you expect, it could mean there’s a problem with the fuel system. The most likely issue is a clogged fuel filter. The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive. This means you can’t get the power you need if you’re trying to accelerate when overtaking or going uphill.While the fuel filter is the most common problem with the fuel system and is the easiest to fix, a lack of power could also point to issues with the fuel line or the fuel pump.
How do I fix the engine oil leakage to spark plugs?
There are three possible causes:1) rings. If the oil control rings are shot, or the cylinder bore is excessive, you'll get oil from the pan up past the piston into the combustion chamber, oiling the plugs. Diagnosis: leak-down test. If you pressurize the cylinder, and can hear air hissing into the crankcase, it's rings.Repair: complete engine rebuild, which these days just about always means "replacement".2) valve guides. If the seals on the valve guides have failed, or the valve guides have exceeded wear limit, or the valve stems have exceeded wear limit, oil may run down the valves into the combustion chamber, oiling the plugs.Diagnosis: leak-down test. If you pressurize the cylinder, and hear air hissing into the valve cover, it's valves and/or guides.Repair: valve job. Much less expensive than rebuild. But be cautious - you could be putting a lot of money into an engine with other issues. You need to establish the baseline health and remaining life of the rest of the engine before doing this (unless you do it yourself, in which case the out-of-pocket costs are low enough that it's no big deal, just annoying, if the engine fails a couple of months later)3) crack in engine. If there's a crack, causing oil to bypass the oil control measures at the piston sidewall and valves, oil will leak into the combustion chamber, oiling the plugs.Diagnosis: leak down test. No air leaking, anywhere, and you're still getting oiled plugs.Repair: replace engine. Me, personally, I'd strip it myself, just to see where it failed, but you're going to need a new block, or head, or whatever failed.
What kind of engine can I put into my 2007 Toyota Corolla CE?
For the cost, time and labor needed, i would just get a different car to start with.. Also depending on where you live in the country depends on if you will ever pass inspection again after you do this work. The Answer to your question is not simple, because it is not as easy as just pull and drop.. All will require some kind of modification, and assuming you want to keep reliability for a daily driver, gas mileage, and an automatic are all things to keep in mind.. If you need to keep an automatic, you need to keep what is in your car right now.. or (1zzFe), they might be able to retrofit the TRD Supercharger designed for the MR-S. although, it may kill your transmission if it is automatic. If you currently drive stick; You can go 2ZZ-GE with a 6-speed out of an 01 Celica GTS (Which would require only small mods) If its not a stick, your car would require some serious modifications prior to the swap.. and again would not be worth it.. Here is a list of Modifiable Toyota's that are little known.. 1. Toyota Cressida - which is a 4 door car that shares the underpinning of a supra, easy to swap a 7mgte into and can be a rocket in sling-shot clothing. 2. 1987-1991 Toyota Camry All-Trac - Easy swap for the 3SGTE which is the celica All-Trac drive train. It would be an AWD rocket with corolla insurance. 3. Toyota Corolla, all years up to 1997 have some great engine options that can make them a blast to drive. 4. Toyota Tercel/Paseo, All years, they all have the option for the 4age and the 4efte or 5efte swaps which can make the little car a rocket to drive.. 5. 2001 and prior Toyota Tacoma 2wd, its an easy swap to the 2, or 1JZ motor. 6. First Generation Matrix XRS and only the XRS, which came with the 2ZZGE motor, and with a little work can put down 300HP. Here are a few that are well known (pricey) 1. Toyota Supra - 1986 and a half and newer are fun with the turbo option. 2. Toyota MR2 1st and second generations are fun, but the first gen has issues with rust so watch what you look for, make sure you look under it. 3. Toyota Celica GTS, only the GTS, and all years offer some excitement, my personal favorite is the 1986. 4. Toyota Celica All-Trac If you find one.. Be certain you are willing to shell out what it will require to fix, because chances are it will need a lot of work.
What kind of engine should I put in my 95 Toyota Corolla?
I'd probably just leave it alone as a daily driver until I found a more suitable platform to build a car on. If you're looking for a list of engines, these have been planted into the corolla: 1zzfe/fed, 2zzge, 3sge/gte, 4age/gze... If I had a gun held to my head I'd go with the 3sgte. The 3sgte isn't a bad motor, it fits, and if anything it's like the cousin of the 2jzgte. The main problem I'd find in this equation is the vehicle which you're looking at dropping it into.
