SOURCE: 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.

Check your oil----is it very high? Put a piece of cardboard under your car overnight, see if you have any leaks externally. If not, then you have an internal leak, which indicates a blown head gasket.

Rough idle can be caused by dirt in throttle body or EGR system, but there are many other possibilities. The service engine light indicates the computer has detected a fault. If you can get a free scan at your local parts chain and post the trouble codes to us we can give you more specific repair recommendations.

Black smoke together with rough idle, but only sometimes


is the "service engine soon" light on?? it should be on and flashing is the car is misfiring. that means spark plug or coil is not firing. if the light is on, scan it with a scanner that you can buy at walmart in automotive section. that will cost you about $60 to buy and you have it for future problems. dealer would charge you alot more to scan. or even some autoparts stores will scan it for you for free. scanner will tell you which cylinder is not firing. start there.

1998 WINDSTAR CSERVICE ENGINE SOON LIGHT IS ON


it's not likely a bad o2 sensor would cause it to run rough, but the catylitic converter, which is what the o2 sensor reads the flow of, would cause the car to idle and run rough.If you take it to an auto parts store to have a diagnostic test ran on it( most major parts stores will do this for free), thecodes it gets would help pin point it alot better.

Service Engine Soon Light


The best way to know what is happening there is to drive a GMC dealer and get them to hook in the diagnostic tool and read the computer memory for present faults.

Auto diagnostic shows multiple misfires/electrical


You have a shorted circuit somewhere. Look at the plug wires for contact with ground.

Maybe your service engine soon light bulb is out. Maybe hook the code reader up to it and make sure its not showing anything.

Let me know if you need some more help.
