well i bought my 2nd 6gc and it had the check engine light on. well we cleaned the engine bay and when we were done i got in the car turned the car on and the check engine light went off?? anyone know what happened??. also after that it drove fine right. then i parked ot try to drive it and it wouldnt go into first gear so we pushed it into my driveway let it run for about 15 minutes on idle and then it worked again what is going on with this??

if its the 95, check your codes by bridging the T1 & TE1 while the ignition is in the on position, but not running. download the BGB from celicatech.com and use that if you need info on how to check the codes, and go from there.

open up your "diagnostics" case under your hood and shove a paperclip in them

its in the "how-to" section on the main page

also, what i found out with mine (1998 gt) is that apparently i cant use this nifty process because i have a odb-ii or something like that

haha yeah the 96+ have obd II.. they have to get the lil tool from autozone or what ever the place is. the paper clip works good.. i have had the check enigne light on for well a year now for my egr valve.. but passed emmissions and thats all its for so screw it.

the ECU stored to code, the problem could still there but just not showing or gone. It could of just been a loose connection or an eratic change in driving style. You could reset the ECU (pull the ECU fuse in the bay (or the neg battery terminal) and wait 30 sec, then reconnect) and check to see if the CEL pops up again.

the not getting it into first gear...I have no clue, maybe...loose shifter cables ? tranny oil needs replacing ? shifter assembly was jammed/not lubed ?

My check engine light would come on some days and some days it would be off.
I found out it was a bad o2 sensor in the front.
It was working some times and sometimes it wasnt.
