Cold starts are awful. Or when it's a damp morning. It starts fine but then the RPM's jump all over the place and the car barely runs. After 30-45 seconds it calms down and idles ok, but at warm idle still does not seem right. The SES light is on. We haven't touched the timing at all (except trying to adjust it to fix the idle, that we read on another threat here) or fuel so I'm not sure why this is happening??? It's even worse with the AC on.
I'm a tuning n00b, my cousin has been teaching me and doing the tune. This is his first LNF though and it's much more complicated than his Buick GSX, so we really don't have anyone to turn to for help. So then I registered here!
I have a copy of our tune, see attached.
Also we have disabled the post cat O2 sensor. Is that the same as disabling the catalyst warm up? (I had a ZZP downpipe)
Anything will help, feel like 2 blind guys trying to find our way out of a maze
