Hello!


Being a new owner of a Camaro 350 TPI -89, I'm in need of some advice.


Due to earlier problems the base timing, then IAC and TPS was re-adjusted by my workshop. The mechaninc however wasn't quite satisfied with how the engine ran, so he later adjusted the base timing down from 6* to something like 5.5-5*. The engine now runs good and I don't really experience any problem about this. (The only thing might be that it's sliightly slow when cranking it, takes a sec or two before starting up).


What I wonder is if it's really necessary to re-adjust the IAC and TPS now, due to the slight change in base timing? I read it should be done in that order but since the car runs fine, it seems unnecessary to me.


Thanks for your help!

Generally you do it whenever you make a change. They also come out of adjustment over time, slightly. If you don't have driveability issues, I'd just leave it the way it is. A half a degree of timing shouldn't affect it that much

 

Okay, thanks for that! I'll drive it a bit more and see how it behaves, then decide what to do.


Cheers!
