Hello, I have a 1986 mustang and one day while driving my rpms wouldnt go down past 1250 rpms. After letting it sit for a few hours and starting it back up it would surge between 500 and 750 rpms. After a week or two the rpms would occasionally get stuck above 1000 rpms, so I swapped out the...
Few months ago I installed a mspnp2, along with GT40P heads and intake on my 95gt, idling has always been an issue but the startup creeps to around 3k and hangs there for 4-5 seconds before dropping down, this is only when the car has ran in the last couple hours, cold starts in the morning...

Hello! I have a 1995 mustang v6 and it is having surging problems. You can be driving a certain speed (even set on cruise) the cars speed will stay the same but the cars rpms will rev out going up and down continuously. When it finally release its pushes or jumps the car forward. No check engine...
Alright guys coming back to my roots here at Stanget hoping to solve this one. Recently swapped a PI 2v 4.6 with a Stroker kit into my 96 gt. Along the way I deleted my EGR because with Longtubes it's darn near impossible to put all that crap back on. Problem is I've had a little bit of a miss...
