So I just got my TPS ohms correct and changed plugs and wires checked all vacuum hoses and everything is good, it does have the cold start thermo and BAC removed. Anyways when it's cold starts right up, and runs fine, but once I get on it and run it hard it wants to die right after a few pulls then won't start for a while?

 

So last night I took her for a cruise after I checked over everything, anyways city cruising she's fine temp wise but as soon as I get in the freeway she overheats and as soon as I get off she cools back down, also I was racing a g35 "smoked it" but the car overheated bad so I pulled off and let her cool down then turned it off, after about 15 min I tried starting it and it just cranked and took about an hour to get it started? And ideas?

 

Sounds like it could be blown. Did it smoke a lot when it started? Does the exhaust smoke smell like coolant?

 

Nope no smoke maybe a little when I get on it, and it does smell super rich and bog really really bad from idle to 1600rpms but it has the throttle body mod so I know that makes the idle rough and hard to get going

 

how long did it overheat and was it driven hard while overhearing? It takes one time of overheating to mess up a motor. compression check time. why are you overheating?

 

Well it was driven hard then overheated fast then barely driven till it cooled down, it's not overheating anymore and runs fine once running and holds boost fine, but it's just really really hard to start. I noticed it has some ground problems and low voltage to the FP so I got to figure out those problems first
