Help...test driving the TTA now it's sputtering?
Took the TTA out today for a test drive and to check my numbers and adjust the TV cable...at 1st seemed to be running fine but then started to sputter. Now it will barely run...there are no mal codes on the scanmaster but it has no power at all...don't seem to be any vacuum leaks anywhere that I can find. Fuel pressure is 43-44 with let vacuum line off and about 37-38 on...BL is on the low side at idle ~116 +/- but seem to come up to 128 while driving, TPS 42, IAC 16. A ny idea of what's going on and what should I check? I thought the trans was acting up at 1st because it started to buck...down shift upshift but then realized the motor was sputtering and almost cutting out.
Thanks,
Scott
