I wish I have a code reader for this one. Any idea why my check engine light come on after everytime I stop at the gas station. Evap. system maybe??

 

check your gas cap.

 

+1 on gas cap and if it is good, then evap system.

 

do the ignition key trick.
on - off - on - off - on
read the codes in the odometer window.

 

I tought that the on-off trick was for the Dakotas only, good to know.
As for the gas cap it's on tight for sure, so unless it's craked ... I'll check it closely.

More to follow, thanks.

 

I had to buy a new cap when I got my truck. I kept getting evap codes with it also, even though it was new. I took a little vacuum grease and coated the gasket and the edge of the filler neck where the gasket meets. Since I've done that (about 1 year ago) I havent had it come back. You could also use petrolium jelly (vasiline). Just smear a thin coat, no gobs.

 

That is a real good advice right there, thanks man, I will give it a try right after the on/off trick.

On-Off trick is not working on my truck, I tried many times and my buddy too.

 

Try again. It should work on a 99. If not, maybe you have an early 99 late 98. This will be the first time I've seen it not work on a 99.
