| Post subject: | Fuel loading up |
I have developed a new problem that has me stumped. as everyone knows I installed a new create motor 3 months ago. It has running fine for over 2000 miles. I took it to work one day with a full tank of gas 90 mile round trip. Going home it started to brake down on me SO reading the helms book i torubled shooted the following items. I set the TPS according to the Helms manuel Its right on the money. I repalced the TPS, CTS ECM, I rebuilt both throttle bodies, the fuel regulators, installed a new MAP sensor , and a new TPS again. Still have same problem Car starts up fine idles at 1200 rpm when cold start then drops to 600 rpm when warm. As soon as you crack the throttle it loads up with fuel and stalls out. I checked for vacum leaks I have none. I have a new fuel pump, but I put a gage on it and its reading 13 psi. I am not getting any check engine light. With a scanner on it while running it was clean. I changed O2 sensor because I had a check engine light that would come on then go out during the whole trip home., I put tester on it it was calling lean mixture and O2 sensor. After changing O2 sensor no check engine lights . But something is telling this car that it is running lean. I have ordered both front and back injectors should be here today i hope if that does fix it. I am stumped big time. Has anyone ever had this kind of problem,???? |
