NEED engine help...
My car is totally stock except for a gutted downpipe(no precats) and apex exhaust. I recently replaced the plugs and wires with oem plugs and magnacor wires. While I was under the uim i replaced a few hard vacuum lines. I bought the car about 6 monthes ago and the guy I bought it from didnt know if it had a rebuild or not. The engine seems strong to me and has even compresion across the board. Now for the problems. After putting it all back together, I hooked up a vacuum/boost gauge and took it for a drive. At idle it is reading 18 w/e the common measurement is for vacuum with no drops. When I give it boost the gauge creeps up to about 2/3 psi and then my engine seems to shut down and die. It bucks and I can hear a pulsing "pss'' sound with every buck. When I let off the gas and kill boost, it is fine again. It back fires and is definetly running rich. Same thing in all gears, any speed. And if I rev the engine in nuetral with enough boost, the same thing happens. Also, when I let of the throttle with the clutch in, it seems to stick at around 2k rpm. It didnt do this before. And when i come to a stop it hunts for an idle around 1k-1.5k. it was doing that before but not so often. And finally... a couple weeks ago I used some chevron injector cleaner and ever sinse then, if the engine is warm, it has a harder time starting. any ideas??? please help me!!! thanks
