Chevy 5.7 carburated engine idles fine,but when I drive it a short distance & stop,It don't want to idle.any ideas ?


The choke not opening up(from cold to hot). Bad air and fuel filters. If you have a mechanical pump, they work or run bad all the time or don't work. If you have an electrical pump, it to could be going bad.

My oil light is on on my 2002 toyato camery it has oil and it has atapping sound when idle what causes this


You could have a bad oil pump. Even though the engine has oil, if the pump is bad, oil pressure will be low, hence the oil light. The tapping could be hydraulic lifters not working correctly because of low oil pressure, or the failed oil pump. See a mechanic ASAP. At a bare minimum, he can run a computer code scan to see if there is something detected by the onboard computer.

Is there a map sensor on a 1992 honda accord


Hard to diagnose over a computer with out the proper technical data, or specs, or more info, but erratic idling could be due to a number of things, from, bad plugs/incorrectly gaped spark plugs, bad knock sensor, bad fuel/contaminated fuel/dirty fuel filter, clogged or partially clogged injector(s), loose belt/bad pulley, faulty computer, dirty air filter, bad O2 sensor(s). I've worked on Honda's since 1984, they do have a MAP sensor, they were normally located on the upper manifold towards the front on some older models, on newer models they are normally on the front-side of the manifold right around the belts and pulley's, on some they are underneath the front plastic covering that covers the water pump, sprockets and most of the front of the motor so you wont see it. The link below is NOT To sell you any parts, it's to show you what one looks like so you may find it on your engine.

A/c doesn't work, temp gauge doesn't work, speedometer doesn't work until it gets to 30 mph, and rough idle in the mornings. could all this be the result of a bad computer?


Very unlikely that it would be a computer problem, it does not control the A/C, or temp gauge. Sounds like multiple problems. A/C could be just low on Freon, if pressure is low, it will not turn on. Temp gauge and rough idle may be related, if temp sensor is bad, the computer wont know the engine temperature and thus not mix the fuel correctly. But there are many things that can cause rough cold engine idle, like dirty throttle plate, or bad idle air control valve. You did not say what engine you have, so this is just general information.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Ruff idle when at idle gets worse when you put in gear


Sounds like a skip, or a cylinder has stopped working. This may be due to no spark (coil pack), no fuel (Injector), or even bad compression (Bad valves, cracked head, or something mechanical.)
Get it checked out.

This happened to me recently on my 2004 Grand Cherokee. It stalled out three times in a month. No one came up with any codes except that my throttle sensor needed to be replaced ($80). After it was replaced, it stalled two more times, but this time the check engine light never came back on. My local Jeep mechanic looked it over for around six hours and could not find anything. However, my amps on my battery was half of what it should be. He stated that the computer may not have enough juice to control the throttle idle that activates when the vehicle is in low idle speeds. He also stated that once you remove the old battery to touch the battery cable terminals together (you can use a wrench if terminals won't touch) for around ten seconds. This is supposed to drain any remaning juice from the jeep and is supposed to reset the idle memory and computer for the vehicle. After replacing the battery, crank the Jeep up and let it run for at least five minutes without ever touching the gas pedal. Leave it to idle and I repeat, do not touch the gas during this time. The mechanic stated that letting the vehicle run for at least five minutes without touching the gas pedal will set the computer for the Jeep to run efficiently with the new battery and will also set the idle memory for the jeep. I did so and you could actually see the RPM's going up and down until the Jeep found an efficient idle setting. Try that, I know it sounds simple, but I tried every else before this, and it has not stalled out since a couple of weeks ago. I'll write back if it does before the end of next month. Hope this helps.
