2001 Toyota Avalon - Answered Questions & Fixed issues


It just can't do that. No way to shut down one side of an engine.
Misfires are caused by lack of fuel, spark, or compression. One of the three is missing. One whole side-that rules out spark. Coil pack design just won't affect one side of the engine. That leaves fuel or compression. Some multi-port injection systems are so-called "bank fired" -that is, one side or bank of the engine will pulse the injectors at the same time, first one bank, then the other. But in the early '90's, some cars came out with sequential fuel injection, which pulses the injectors individually, following the firing order of the cylinders, more precise fuel metering that way. I would have thought that an Avalon would be sequential injection, but you could check. Anyway, you need to check if the injectors are working on 2, 4, & 6. The power wire to all injector systems is a single wire that is spliced to each injector. Conceivably, the splice to that bank or side may have broken. With key on, every injector should have voltage at the injector connector. Only two wires to each injector- a power wire and a ground wire. If no power on 2, 4, or 6-that is probably it. (On bank fired injection, all three ground wires on each side splice together before the ground wire goes into the computer. With sequential, each injector ground wire goes to the computer separately.)
Beyond fuel, it is possible that the fuel/air mixture is being affected on only one side. If you have a noisy exhaust leak on that side, it could lean out the mixture.
Finally, low compression will cause a misfire. Possibly, a camshaft on that side is not in time. Only way to check is to do an engine compression test.

It sounds like possibly a bad CV joint. Do you hear a clacking sound when it jerks? There are other possibilities, but just take these possibilities one at a time until you find the problem.

check coil pack and injector harness for that bank.

Backfire often means lean fuel condition. Check for correct fuel pressure and report here.

This could be a number of things....Really need more info...Because if it shuts off when you apply the brake and let off gas at the same time it could be an inoperative brake power booster or loss of vacuum..( vacuum leak )..Try this but don't touch brake.....If it dies without touching brake It could be too many things just to try and guess which is the inoperable component..To save time,money and headaches you need to hook it to a scanner...Has it been tuned up..?.What is engine size..,what is mileage..?.Did it happen all of a sudden..Does it get worse or go away at times...and so on..More info is needed for me to just guess...It may be a Throttle Position Sensor..O2 sensor....etc...too many to list...Save a Headache and have it scanned...Auto zone and some parts stores will scan it for free just for your business.....Although in some cases ONLY a DEALER SCANNER will be needed to find exact fault....GOOD LUCK....

CHECK FOR VACUM LEAKS. IDLE AIR CONTROL VALVE CAN ALSO CAUSE THIS

Check fuse box first, location and what each one controls in your service or owners manual. Then check connections under dash also

I don't think I have seen an oil drain plug that is left hand threaded, it may have been put in wrong and your thread is stripped either on the plug or the oil pan or both. Good luck

It'll be a section of wire inside the wiring harness somewhere near the device it protects. It'll be a short section of flexible wire a little smaller than the wires that it's spliced to at both ends. The idea is that if enough current flows through the wire to burn up the wire, the fusible link will burn through first, sparing the rest of the harness.

If the airbag light is on, there is a failure in the airbag circuit, and your airbag may fail to deploy in the event of an accident.
There is no "reset." You will need to have your airbag system serviced.
