Make sure that the idle motor is working.When you start it should run about 1200 rpm for a few seconds then go down to 600 rpm If not it may need cleaned or replaced.

I have a 1993 Ford Explorer that goes into high idle when I put in gear. It does this when the engine is hot or cold.


On some cars there's a speed sensor on the clutch or transmission. That might cause an idle problem.

JUST REPLACED CARB ON MY 1992 CHEVY SILVERADO WITH A 4.3 LITER. NOW IT STARTS AND RUNS FINE UNTIL IT WARMS UP THEN DIES AND WONT START FOR 30 MIN


How many rpm's is it running at when you first start it up and it is running on the choke? Does it gradually start to idle back and then start to die r does it do it all of a sudden and dies?

When running with the choke on, it is on the high idle circuit of the carb, as it warms up the idle should slow down and then idle in the 800 rpm range in Park, 650 in Drive. This will be the low idle circuit range. This transition inside the carb will cover an idle air bleed hole in the venturi of the carb and lean out the mixture. If you notice that the carb smells gassy and black rich unburnt gases are coming from the tailpipe, the problem is located within the carb and requires a carb tech to do a rebuild of the carb. You could try a good carb cleaner like Lucas by putting it into the gas tank, in case you just got a bad tank of gas, but that is just a bandaid for a more deeply rooted problem. Get the carb rebuilt?

CAR RUNS GREAT, STARTED DIEING WHEN A/C WAS TURNED ON, NOW A FEW DAYS LATER IT DIES EVEN WITHOUT A/C ON, RUNS BUT WILL NOT IDLE


CHECK IDLE SPEED SHOULD BE 650 - 850 RPM. IF IDLE TOO LOW AC WILL PUT DRAG SLOW DOWN ENGINE CAUSING ENGINE TO STALL IF IDLE SPEED IS TOO LOW.

My 1997 Chrysler Concord idles at 2500 to 3000 rpm when first started and when it warms a little it idles at 2000 rpm and stays there. When I start it right after I turn it off, it starts at 2500 rpm then...


Maybe a short to the TPS or something shorting it out. There's also the IAC that really controls the idle but usually it will cause the RPM's to go up and down a little erratic if bad. The MAF sensor can cause major problems as well but since you already swapped the TPS and it helped and then stopped I would focus on that sensor and especially it's wiring to and from the ECM. Be careful with the sensor signal wire to the ECM can blow it if more than 5v passes or spikes.

The idle air control valve is what regulates incoming air when the engine is idling. In some cases these can malfunction and cause intermittent issues with stalling at idel until the IAC dies altogether.

1997 jeep grand cherokee. low idle 500 rpm, runs fine but letting off the throttle it dies. starts right back up fine.


Most of the time an engine is supposed to idle at 5-600 RPM in Driveif it's not you can up the idle. But you also may have a vaccume leak.

Idles low when ac/heat is on and lights dim


fix the idle speed to 850-900 rpm
check the alternator and voltage regulator as the voltage should read 14.5-14.8 volts dc at 1000rpm or higher regardless of what is running
have it bench tested by an accredited auto electrician

Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.
