i have a 88 trans am 305 auto and the car was running great, decided to put a timing light on for the hell of it, found that it was way off, so i fixed it to where its suppose to be now the car dosnt run so good, its drives but when you punch it it dosnt pick up quick, also wont shift out off 3rd gear

 

I'm not seeing where there's anything hard to figure out here.

Sounds like you need to un-fix it.

Put it back where it was.

 

I normally don't like your way of putting things, but that was one of your funnier ones Sofa. I literally busted out laughing.

 

I have to agree, if it's not running right, put it back.

 

yup, sugar coating wouldn't dare get within 100 miles of sofa!! BUT he is always right.

 

WEll I don't know about "always"; but in this case, I'm not trying to be insulting or funny or anything, just logical. Sometimes it just turns out that way.

Logic is critical, always, to EVERYTHING.

Of course, there's no guarantee that wherever the timing was, was "perfect" or "right" or "not subject to further improvement" or any such thing; just, it should be rather obvious that where it was, it was better than it is now.

Mu suggestion to the OP would be, to mark it carefully where it started out at, so he can always go back; then pack the timing light carefully away, back in its box; then adjust it in small increments until "The Best" is found. THEN AND ONLY THEN, get the light back out, see where it ended up, and write that number down (and make a new mark), so that it can be put back to this newly found "Best" spot in case anything like this should ever happen again.

 

Good stuff.

To the OP, you need to disconnect the EST bypass connector, then set base timing at 6 BTDC.
Shut the engine off, then reconnect the bypass. this was the SES light will not stay on.

 

On my 84 at least, I can pull the ECM fuse to accomplish the same thing.
