Is there anyone ever had this problem? I took the hpp3 and changed the tire size's for the speedo and this was after pcm4less done my ecm and it was running good at the time.After useing the hpp3 now the car wont idle and the ecm is dumping fuel so bad in the engine that it's fouling the plugs.I have scanned the ltrims and the will start - 4or 5's and then time you touch the gas the y goe 0.0 good right? No because then you can start smelling the car loading up with gas,and you can try to put it in gear it's a a-4 and try to drive off with it too clean it up and it just dies. Any help would be greatly apreciatted

if you have headers and no cats, then you need to take off COT. mine was running terribly rich after i did my swap, but when i changed that, it was alot better...

yes I have mac. mids. with no cats but it has been running fine like it is for about two yrs. thats what is bothering me so much. COT?

COT ~ Catalictic converter overtemp. make sure it is turned to false or you will get major fuel consumption!

I also have the simm's on the car now they could be bad.But it would be strange for it all to happen right after useing the hpp3

Are you sure the HPP3 was for your car's correct year?

firebirdls1us

yes I bought it not long after buying the car in 99. I have a h/c, all the bolt on's with mac. mids. and I had it mail order tuned and it was running pretty good but I thought there was more there.So it was a stupid mistake to hook the hpp3 up anyway it just over rode the tuning.But the thing that gets me is before the tuning I drove the car for about a week with no problems other than idleing problems. So if it set everything back to stock why wont it run about the same as it did?It happened after several dyno runs I'm thinking maybe a bent pushrod?
