Okay, well we know we have a vaccum leak but I thought I fixed it. Nothing changed. Also, he brought me home tonight, there is a new noise. It sound almost like something in the motor/Intake that has a rough nocking noise, if you are playing with the gas. (ie: punching the letting off then punching it and letting off, rpms go off 1.5 to 2 then down to 1.5 and so on). I plan on checking for a vaccum leak with the starter fluid later. Ideas on the noise?

John



oh yeah 86 GXL with new motor

you mean replace or adjust, and could this cause lack of idle if it is out of wack

TPS could be your idle problem though. Adjust it.
