117826, Very rough driving and high egt's
Posted by Nightfall, Oct-18-07 12:44 PM
My car has been acting very strange lately, like when taking off from a stop I have to give it more throttle to get it to go, and even then it feels like it just don't want to. Shifting at 3k rpm without boosting my egt's are hitting 1500. If I let off the gas and keep it in gear it "bounces" back and forth, especially if the a/c is on, like it has bad motor mounts(which I know it's not because I have new Prothane mounts.) It's not missing or anything, rpm's drop quicker than normal when letting off the gas while shifting too. I do have a small exhaust leak at the head/manifold and the compressor housing on the turbo leaks boost a little- http://forums.2gnt.com/dcboard.php?az=show_topic&forum=8&topic_id=101605&mesg_id=101605&page= I plan on fixing those leaks and doing a compression test this weekend. Any help would be GREATLY appreciated

Some info on my setup:
Hahn stage 2 16g/fmic 7-8psi
Vortech sfmu/stock injectors 3.62 disc/Walbro 255
Fuel pressure 50psi/idle/20vac - 62psi/0 vac - 100+psi/full boost
BKR7E NGK's .33 gap MSD coil/wires
Idle egt 950-1000 - 3k rpm/0 vac/boost 1350 - full boost 1800 and would probably keep rising if I don't let up

sounds like it's running very lean with those kind of EGT's
