Try replacing the spark plug wires, and distributer cap, I found arching from wire to cap on mine, and mine was doing the same thing.

The ck engine light should not be ignored, what sensor was shown to be bad ? Have it scanned again and replace the sensor that is bad if it still runs rough you might want to consider a tune up. Plugs, wires, fuel and air filter's and clean the throttle body with some gumout. It could also be the IAC motor Idle Air Control. Good Luck

SOURCE: 1999 Toyota Camry, poor Idle (<250)

start with performing a tune-up (if not done recently), replace sparkplugs,wires, air filter and have also the IAC valve and intake throttle body cleaned. If problem persists, have the timing checked. Hopefully this helps

SOURCE: i have a 1995 chevy lumina 3.1 and upon starting

you need a tune up...plugs, possible wires too, they might have a lot of carbon tracking deposits on them ...clean (IAC) sensor, if you"ve never cleaned it, believe me it"ll be dirty.. and then make sure you completely clean you throttle body too inside and out! but wait an hour after before starting to let it air dry...clean air filter or replace it, and replace fuel filter if it hasn"t been replace in a long time. also after you"ve done this purchase a can of Sea Foam fuel system cleaner $10 and pour 1/2 can into 1/2 tank of gas and drive around even if its running "a little rough", for about 30 minutes and this should clean out any fuel injectors that may be possibly clogged up! if you you cant drive the car but will idle only after cleaning (idle air control), pour some seafoam in the tank and let it idle for about ten minutes then try to see if it will run. If none of this works then you probably have a fuel pump not putting out the correct pressure!

Rav4 hesitation at 2000rpm sometimes limp mode .only hesitate when driving not idle


Many drivers have run across this problem and, unfortunately, it could be just about anywhere in the engine. It could be a problem with the idle air control valve that, if it is performing poorly, could cause the engine to hesitate and die.

Or it could be a problem with the manifold air pressure sensor or manifold air flow sensor. Again, if either of these devices is performing poorly, your RAV4's engine could also hesitate and die.

Or, it could be the O2 sensor in the emission control system.

Finally, it might be a plugged catalytic converter or a slightly plugged converter. (This is an expensive fix.)

This type of problem, since it could be in so many different systems, is very difficult to determine. Many car owners have reported similar problems with other model autos and due to the nature of the problem they have been unable to find the cause.

And, while I might be tempted to say it is the cat or the O2 sensor as an expedient answer, I would be doing you a disservice. Instead, I would suggest taking your vehicle to an independent garage where, if they have the proper diagnostic tools and programming, they may be able to find the problem. It may lie in any of the systems I mentioned and I would suggest, of course, having them checked out first. Beyond that, it will likely take some extensive diagnostics to find the problem, unless, of course, it is one of the areas I suggested and it pops up early in the engine checkout process.

Engine missing is a vast subject and calls for number of things to examine. What are the problem symptoms? Is it concerned with one or more of the following?
- Rough idle, stalls or misses.
- Engine hesitates/ poor acceleration.
- Engine diesels (runs after ignition switch is turned off).
- Muffler explosion (after fire) on deceleration only.
- Engine backfires.
- Engine rattles at idle speed only.
- Engine rattles at all speeds.
Please mention if there is some other symptom.
Thanks.

The car will pop alittle when you try to start it...It wants to start but wont..replaced the fuel filter,plugs.I have spark to all plugs..I can squirt gas into the intake and it will run but will not idle...


usually when a vehicle backfires, it is caused by the timing or a bad crank sensor. symtoms of a bad coolant sensor are--poor cold idle, stalling, ( rich mixture,retarded timing) slow idle speed, cold hesitation or stumble, and poor fuel milage. check coolant sensor first. good-luck!!

Poor Idle, dies at stopsigns


I have used this fix for your problem for 20 years.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
