I own a 91 Firebird V6.

The starter went, so I had a local mechanic install a new starter for me.

I picked the car up this morning on the way to work. I was rushed for time. I started it and noticed the check engine light on right away. My office is only a few blocks from the mechanic, but it did feel like the car was running rough and down on power.

On the way home tonight, the check engine light again come on right at startup. The car is WAY down on power and I had severe trouble merging onto the highway and making it up a hill near my house. Furthermore, if you hit the gas hard while it's rolling, it stumbles and the RPMs drop for a second. Also, if you floor it, the RPMs rise to about 4000 then SLOWLY climb higher, while the car barely accelerates and feels so, so weak.

What could the mechanic have done while replacing the starter to cause this?

Any other ideas?

Feedback is appreciated.

 

I dont know what to say,but I would take the car back and tell them what happened

 

maybe, for starter replacement he disconnect the battery......

The 3,1L V6 has a problem with this after reconnect. The ECM must relearn the tables (BLM and INT)....... let it complete heat up at idle until the engine blower starts up. Then testdrive the car and see what happend's.

I read often exact your problem at german massage boards..... hope this helps.

other option:
You see the SES?? read the errorcode and see what it say!
Check the connector at the O2 sensor, it's not so far from the starter at the V6 engine!
also check the groundstrap to the block!!

 

Good information, thanks!
