After gasing up my truck, and going threw a auomated car wash ( truck was running the whole time ) the check engine light came on, and the truck began running rough, even to the point of back firing on acceleration.

I limped it home and pulled off the batery cables waited for abought ten mim , hooked up the batery cables, truck now runs awsome.... In fact better ...

By bigest fear was I may have blown a 02 sensor, and I wounder for that brief period of time, why the truck was running like a $3 hooker.

Gas cap was tight, truck has the orginal tuning, and I have been running dual ex for two and a half years, What causes the check engine light to come on?

 

you need to read the code to see what it is ....need more info

 

I don't have a OBD 2 reader and I'm not going to dodge to find out.

If the Check engine light comes again, and I can't clear it, Than I will go to the dealer.

Just woundering out loud what are the common issues that set off the add money light in the dash..

 

If there is an auto zone near you they will read and clear the codes for free. I got a code reader that clears codes for like $50 from wal mart.

 

If you have a harbor freight near by, you can pick up an obdII scanner for $18

 

sensor connection got wet in car wash confused computer dried out and now fine

 

makes sense to me!

 

Harbor Freight is the $hit

 

in CA autozone no long reads codes due to a lawsuit. i picked up a code reader/eraser from them for like $30, now i wish i would have went to harbor freight.
