Hello, trying to get some advice, car would start and run fine. Few things I would like to replace just haven’t had the time like the mufflers, both have serious holes. Recently, it starts and only stays on by keeping some gas on the pedal. If I let go, idle goes down as it should but then gets erratic, up and down and eventually cuts off. Dont know last time fuel filter was replaced either. See if anyone has had or having this issue.

look at the big air hose over the engine...if it has come loose or ripped it causes havoc, but will start.

Thanks, I have two spiders and have had issues with that, however that air hose is good and tight.

I had a similar issue with my 89 - the idle would rise and fall between 1000 and 1800 rpm every few seconds. Turned out to be the TPS out of adjustment. There's info on this forum on how to check it.
