90 rough idle during cold start
so basically when i start my truck from a cold start it revs up then just falls and dies. i usually have to start it like 5 times with the foot on the accelerator for 5 mins to warm it up, then it idles a little roughly (not too horrible). it also hiccups a lot during low cruising in 1st, 2nd gears unless i'm accelerating, but not in the higher gears. once it's running and warm it runs fine despite hiccuping while i'm barely accelerating in low gears.
i've changed my air filter, fuel filter, pcv valve, added injector cleaner, gonna have my friend help me change my spark plugs tomorrow and check my codes, cleaned out my IAC, battery and alternator are in good shape, no C/E light, and so far nothing has worked. i'm just wondering if any of you guys have any other ideas what it could be before i take it in to have it looked at. i've heard it could be the fuel pressure line or vacuum hose.
any thoughts and or help?
