High Idle-TPS not hooked up

g_rizzo · 10-21-2011, 08:11 PM

i have a 90 turbo, with the TPS hooked up the car will surge at anything higer than 1500rpm and is not driveable. I have unhooked the TPS and it will not surge put the car seems low on power and will quick shift not going above 3000rpm unless i push it. can't seem to find the reason for this, i have installed a new TPS which didn't change anything, checked any visable hoses, cleared all computer codes. the car has new plugs,wires, coils, i have cleaned the iac valve, replaced many hoses. I need ideas to help find this problem
