bumble zee Posted August 22, 2005 Share Posted August 22, 2005 Alright, here is a little background information, 81zxt engine and efi intercooled 370cc SVO injectors (Brand New) stock T3 turbo No emmisions 76 intake Here is the scenario; You can really feel any thing in first and second because they go by to quickly, but 3rd through 5th you can definatly feel it. It feels like it is losing power for a split second then its back to normal. This is a completly random happening. I have looked in the archives at zcar.com and I got alot of TPS results, but the turbo TPS only reads idle, correct? My fuel pump is going bad and needs to be replaced, but according to my a/f gauge it is still 2 bars rich at WOT. I have regapped my plugs to .040 the other day and it didnt seem to make a difference. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
bumble zee Posted August 22, 2005 Author Share Posted August 22, 2005 Figured it out. Plug gap was to large I think. But reset the TPS and changed out the ECU. Quote Link to comment Share on other sites More sharing options...

Guest bastaad525 Posted September 3, 2005 Share Posted September 3, 2005 yeah I just had this happen to me too. Stock NGK's I had them gapped to .050, thinking I could get away with this since I'm running an MSD and blaster 2 coil. But yeah, every so often when I'd hit boost, the car would surge or buck, I'd hear a loud pop from the exhaust, and get a big puff of smoke. So finally I figured out that "hey that's misfire!" (yes I'm slow sometimes), so I pulled the plugs and regapped them to .035, and haven't had the problem since. Quote Link to comment Share on other sites More sharing options...
