SOURCE: rough idle

check you throttle position sensor first then fuel pressure regulator, then fuel pump. i have a 92 and had to recently do a massive overhaul. my rough idle was caused by a malfunctioning tps with a small exaust leak causing it to race and an intake manifold gasket. also check your idle speed adjustment settings.

SOURCE: 1991 Camry running rich

check for vacuum leaks especially around the intake manifold gasket. Although the engine appears to be running rich, it could also be misfiring due to being too lean in one cylinder. When the cylinder doesn't fire the charge, it goes into the exhaust completely unburned and looks like a rich running condition due to the unburned fuel. If it is a vacuum leak causing the problem, the engine will run fine at road speeds but misfire at idle and not pass smog.

I replaced my iac valve on my 1997 toyota pickup t-100 3.4 L runs smooth in park but when i put it into drive runs a little rough ?


It sounds like your spark plug coils are in need of replacing.. Engine run rough when they are failing.. Easy to replace most times and not terribly expensive, do your plugs wires and distributor at the same time .. A couple of signs that show when you are needing replacement.. Fuel economy starts to fail , car will run rough or sound like it's missing ( not enough fire going through the plugs from the weak coil

I have my toyota noah 1az with the problem of Too much smoking ana backfires


It sounds like the engine is running very rich, causing excessive exhaust and exhaust heat. The exhaust heat ignites the unburned fuel in the exhaust and causes the backfires. I'm guessing the engine runs quite rough with a noticeable decrease in power as well. You need to determine the cause of the misfire and fix it. How long has it been since the spark plugs and spark plug wires were replaced?

Hi i got a toyota tarago 96 model that wont start my wife was driving and she heard a bang then the car stopped in the middle of the street so i changed filters n spark plugs n pumps still no start


There are videos on you tube for diagnosing vehicle no start problems ! Rather then just replacing parts . Testing for spark and fuel pressure and engine compression . Timing chain problems etc... My advice to you would be take your vehicle to a qualified repair shop . Save yourself some money . You spent how much already ? i changed filters n spark plugs n pumps still no start !!!!!!!

No power when driving, runs rough, spark plug are new but look black when removed which indicates running too rich. The computer fault code says 14 which is the ignition signal circuit but I don't know...


Replace your entire distributor assembly. Your primary or secondary coil is compromised. Running rich because of weak spark. If you do a spark test, you will not see a bright blue spark if I am right. You will instead see a weak, almost orange spark.

Hello. my 2000 4runner v6 has been running rough. when i start it, it runs fine untill it warms up. then it begins to miss. have replaced spark plugs, and battery but didn`t make a difference. diagnostic...


Change your oxygen sensors - they're responsible for feedback that the computer uses to determine the air/fuel mixture. They usually are good for about 60k miles and then start to go downhill. When they get to a point that the computer won't trust them, it ignores them and runs on preprogrammed fuel maps that run excessively rich (too much fuel) to safeguard the engine. You've probably seen a decrease in fuel mileage as well. And the O2 sensors have to be up around 900 degrees before they'll work - the car ignores them until then. That's why you run fine after a cold start but run rough once the car is warmed up.

The O2 sensors you want to change are in the exhaust system between the engine and catalytic converters (the "pre-cat" sensors). There are O2 sensors after the cats as well, but those are used comparatively to determine how well the cats are functioning. The primaries are the ones used for fuel mixture. If it's been this way for a few weeks or so, I'd put new spark plugs in as well - rich fuel conditions can foul them and contribute to the rough running.
