I have a 85 gsl, i've been driving this car for months now with a few problems. Today i was driving and everything was fine then randomly it started choking and wanted to die. when decelerating in gear it would begin to backfire and kept getting louder until i pressed the clutch in. I floored it home and was probably the slowest car ive ever drove.

My fuel pressure is at a steady 3psi, my plugs/wires are good. MSD coil is good.

Well after it got home and cooled off i changed the fuel filter and checked that after burn hose thing above the mani. and it was fine. I started it up and it ran just like always. Well, when it warmed up (1/4 way up the guage) it started to choke and sputter before dying. But i can re-start it no problem and runs fine for a min then dies again.

I drive this car everyday...any ideas??

THX!

 

Does it smoke at all? I worked on a car a few years ago that would leak coolant into the intake (from the o-rings), but only when it was warm and the cooling system was up to pressure.

 

I didnt notice any smoke or a smell for that matter. but when i got home it was smoking around the carb. but i was also dripping gas on the motor.

 

also i noticed that when the temperature outside drops and i down shift, when it engages i hear a squeaking... usually just 1st and 2nd gear

 

Could be your leading ignition or ignitors failing when hot. Next time it does this
see if your getting spark to the leading plugs.

 

ok im gonna try that today
