Car is running RICH
Well the car is running really rich, so I went to advance auto parts and got a new coolant temp sensor for it and was told there is one on the intake manifold.......not seeing it. Could you guys point me in the right direction?
The car runs fine when cold, but once at or close to running temp it is just bad....it feels like it is loading up until xx rpm's and then it lets go and make the power it should. I'm just tired of trying to figure out the bugs on this thing lol. Any suggestions appreciated. The guy at advance is pretty knowledgable he started me off with this, but I can't find the sensor besides on the heads..

You can smell it's way rich, it's been dynotuned..no codes but we plugged it in at advance and it said computer not connected or something?? I got a mailorder tune and then took that same pcm to get dynotuned..

you say it smells rich...do you have the emission components still on the car?
Do you have the vacuum line connected to the Fuel pressure regulator?
I have yet to see a car with a decent size cam in it that doesn't smell rich.
I don't mean to sound like an ***, but without verifying air fuel ratio there is no way to know if the car is rich/lean by smelling it.

Thanks aaron, and Chopstix, recently it just started REALLY smelling rich. Before it was just the typcial smell of no cats with cam smell, it's overdone now.. Before it ran fine and didn't have this problem now you have to roll windows down to get fumes out it gets so bad. before it wasn't anything like this..

Where would I look for a fuel leak? And I havn't had anything done to the exhaust between the car running well and like **** so I wouldn't think I have an exhaust leak. Once the car started running horribly, it has started smelling alot more. You don't only smell the fumes in the cab, there is just so much out the back pipes it ends up gettin in cab.. I guess there may be a fuel leak?? I figure I'd see it under the car eventually though wouldn't I? All I've seen is a couple drips of oil with the new oil pan gasket.

if you can't find any leaks, put in a new set of plugs....then immediately make a WOT pull, immediately shut off the car and pull a couple plugs and read ai/fuel off the plugs. This will tell you if the car is really rich.
here is a link to reading plugs.

Sounds like a mechanical condition and not a tune issue.
