I started my day off today by changing the 190l/ph pump out for the stock unit, this did seem to help as the car started well and was a bit smoother. Then when I was just about to set the timing it died and it was time for break. I came back to the car after and she would not start, so for half the day I was going crazy trying to find the problem there as I really didn't think it was from flodding at first since it was running when it died but sure enough it was flodded big time. I pulled the plugs and blew out the cylinders, now the car starts and I am able to get the idle to stay at 1500rpm and not a bit lower as it just starts hunting like crazy and dies.
Now I hooked the car up to a breakout box so I could check the values while running and hopefully find something wrong. I feel I did, this is the info I have from my tests.
MAF@ 1500rpm- 1.49-1.53v
TPS 2.93v
MAP or as it is now BP 3.46-3.47v
I had to stop the car as when I was setting in the seat doing all these checks I noticed the floor getting very hot, so I checked under the hood to see what was up and the converters were both glowing red. So I am not to sure but I am thinking now those are garbage. It was then the end of the day so I turn everything off and had to goto work.
One other thing and I really think this is a BIG deal, I was checking the TPS engine off key on with the breakout box and found I was not able to get it to go lower the 2.37v now this I am thinking must have a ton to do with why I am not able to get the car to idle and why it is running so PIG rich. I took it off and was still not able to get it to go any lower. Now keep in mind this is a new TPS that came with the BBK TB, so I took the old TPS off the stock TB and had the same findings.
I have a ref voltage of 5v and when I goto WOT it does as it should, it just wont go any lower than 2.37v. Should I try putting the black wire staight to ground or does this sound like another problem I am looking at?
Oh and for OverKill I am running stock 19lb injectors with a stock FPR and when I turn the key on engine off I have 35psi and when cranking it goes to 40psi.
Thanks for all the help with this everyone, tomorrow is the last day I am going to have to get this solved as I finish school friday and star my stage on Monday and won't be at the school anymore so the car has to leave.
