I have a 92 Ford Taurus SHO and it has started to rev up and down from time to time at idle and then the check engine light comes on. If I turn it off while it is doing this it doesn't want to start back up and sometimes I will have a strong gas smell. The starter will crank and car wants to start but wont then it starts up and runs fine

IF YOUR CHECK ENGINE LIGHT IS ON---MANY POPULAR AUTO PARTS STORES WILL "CODE" YOUR VEHICLE, USUALLY FOR FREE!

WRITE DOWN THE EXACT CODES (LETTERS AND #s) YOU CAN POST THEM WITH US, AS SOME CODES CAN BE "INTERPRETED" DIFFERENT WAYS.

SOMETIMES THE PART STORES WILL OFFER A SOLUTION TO THE CODES (THE BIG GUY HERE AT AUTOZONE HAS BEEN REAL HELPFUL IN THE PAST FOR ME)

A VACUUM LEAK WILL ALSO CAUSE THE RPMs TO FLUCTUATE

KEEP US POSTED
