Car stalls on start, seems boggy in lower rpms, rich in high rpms?
Ok so i got my o2 sensor installed now and im not throwing any more cels. Car feels better but something is still amiss. Here are my symptoms:
- On start up car will almost always surge up in rpms then die unless i give it some gas to keep it alive for the first like 5seconds, then it will hold its own idle
- In low rpms in any gear if i punch it the car doesnt pull, it bogs, then pulls; almost like its flooding with gas or spark is blowing out on a cylinder or 2 then it recovers and pulls fine
- If i gradually excel in any gear i can feel it pulling but as soon as i punch it, things seem to go dead rich and it stops pulling, doesnt bog or anything just makes alot of noise but doesnt increase in pull any
Any ideas what could cause these symptoms? Im thinking maybe the fpr took a ****? slipping clutch? car is stock aside from lightened flywheel and stage1 clutch

I'm seeing sort of the same problem. I'd like to see some answers for this as well. 
but only on startup

Re: (turbotime)
My car really only has the dying problem when its cold outside, I'll start it and it'll rev up and act like its missing, then if I don't give it gas immediately and hold it at like 4K RPM for like 30 seconds it'll just die. Never has a problem on a warm start up.
I don't believe its a Main Fuel Relay problem, I've already replaced mine and that hasn't cured the problem. However if yours has never been replaced I would suggest it on a older car.
I am definetly noticing the bog issue you are speaking of, I can floor it down low and I pretty much get nothing and as soon as I get around 4K RPM it'll start pulling really good. Blows alot of soot, definetly running rich.

ok so i took the vac line off the fpr and it idles great now, doesnt die on startup or anything anymore, and the driving seems improved although there is still slight bogging
so does this mean my fpr is ****?
