SOURCE: why my 2002 blazer might stall but idels good

Could be throttle position sensor, a air mixture sensor or an oxygen sensor. If oxygen sensor then replace all of them or you will strain the others and then you will have to keep changing out the oldest on like a cat chasing its tail. smile.

SOURCE: car starts then dies

You've got a whole bunch of sensors on this car. You need to put an OBD1 scan tool on it and see what the codes are. OBD1 is very vague but may pin point you to the problem. Sounds like a bad Idle air valve/sensor. Could be a throtte positioning sen. More than likely cause in my educated guess, you've got a bad crank position sensor. If not that than its a cam sensor. good luck

The torque converter clutch could be stuck, which would require transmission removal to repair.

May be throttle position sensor. The engine light comes on because of afault signal from one of the sensors. Going out is temporary. After 3 events, the ligh will come on again. It needs to be scanned to find the problem sensor. more than likely the TPS. Good luck

Which way do I shift my 3L Toyota hiace fuel pump for a smoothe idle it starts fine but idels rough and moves off weak ?


Best to have codes read if the engine light is on. start up and rough idle are different. Rough idle can be different things. When is the last time you had a tune up?

Sound like your alternator is shot. Do the test ..After you charge the batery or get it boosted if you remove the positive battery post OFF the battery and the engine dies right away your alternator if shot .

I have a 2003 GMC Envoy XL. I replaced the battery yesterday and when I started the car, the engine had a VERY rough idle, died a couple of times and then the SES light came on. I was told to drive the car...


When you disconnected the battery, the PCM (power control module) was reset to factory default. You can try driving it with several engine on/engine off cycles. Get it up to 50 mph each time so the computer can recognize the transmission operation also. Hope this helps.

My 03 silverado 5.3 will start. idle is a little rough. when i get to 30 mph i loose power and runs really rough. shifting is hard and barely pulls itself up hill. just replace intake gaskets last week


Try taking the positive battery cable loose for 2 or 3 minutes, this will allow the computer to reset. You probably will still have a check engine light but should run until you can turn it off.

MY 2005 SILVERADO STOPED RUNING WHILE DRIVIN WONT START NOW. NOTHING IN THE TRUCK IS WORKING


Fried ignition switch will do that. It's in the steering column and controls all power to everything but if it cranks then it's at least mostly working. Check battery and if drained then possibly the alternator went out. The ECM can be shorted out by a bad sensor but usually act up for awhile before dying. Dead ECM you can still crank motor. Crankshaft sensor would kill engine if bad and no start but car would still crank.

2000 f-250 running rough, overdrive light flashing


Get the codes that were saved when the "engine light" came on and post them here. (You can get them retrieved for free from Auto Zone).

I'm going to take real *wild* guess that somehow that rough spot you hit actually impacted the oxygen sensor and disconnected it or damaged it.

Truck losing power and service engine soon light on


Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.
