'm trying to get my car road worthy, and I'm having a couple of issues still. Here's the car:



88 GXL with a Complete TII drivetrain swap.



Street ported intake and exhaust

All emmisions removed

Throttle body mod

3" Rb exhaust

Rtek 1.7

Greddy 720 cc secondaries and Witchhunter cleaned, stock 550 primaries

Autometer cobalt electronic boost gauge

Walbro 255Lbh fuel pump.



So the the first problem is this> The car wants to die, whenever I let off of the gas. Sometimes I can get it, to keep itself running, but it's @ 2500 rpm. I'm forcing it there by using the adjustment screw. While it runs I see 15in? of vac on the boost gauge and when I rev it, It'll get to 0. I've driven the car in around the neighborhood, and it wants to buck during light throttle.



The second problem is that the temp keeps rising to 3/4. It doesn't happen for quite sometime, but it keeps happening. I think it may just be taking more to fill, than I thought.



There is also a possibilty that 2 of my vac lines might be switched. I'm running the primary injector air bleed, and the FPR vac lines, right next to each other. I don't know if I have the line coming from the LIM, or if it's the one, from near the primary injectors. How can I figure out which line is which?



All of the other Vac lines are capped, except for the one on the top of the UIM, facing the passenger fender. On that nipple, I have a vac line connected to a splitter. That splitter has the vac source for the Boost sensor, Boost gauge and the Air bypass valve.
