Okay, well I've been having issues with my truck for years now. As some may remember my truck was heavily vandalized by a group of students at my old college. Fast forward three almost 4 years later. I have gotten it back to being derivable. But it still have a strange problem that I can't figure out.
When It is started from being ice cold, it fires right up on the first crank, will run great for about a min, then it starts to surge really bad to the point were it sounds like it has a miss fire, sometimes backfires out the exhaust, until it warms up then it idles great, and runs great. If I put a load on the engine the idle will sometimes sorta even it's self out a little bit. Say if I turn on the heater to full blast, the idle also starts to choke on it's self if I turn on my backup lights when I am reversing. Never had that problem before. I know that some may be yelling that it's the IAC but so far it pass test via my ohm meter and the good ole, "unplug it to see if the idle changes". It is new (which doesn't say much now a days), I have taken it off and cleaned it as well.
To get my truck back into running and driving condition I had to do the following after my truck was vandalized. PLEASE READ! what I have already replaced, fixed and diagnosed before telling me to do something that I have already done. thanks
New fuel tank,
both fuel pumps new
New fuel filter
New FPR
New coil
Tune up, plugs, cap, rotor, wires, PCV, air filter, oil change, ALT PS belts new
New fuel injectors
Cleaned out the fuel rails
New water pump, thermostat
New timing chain, reset my timing
New IAC
New MAP
NEW TPS, adjusted the TPS sensor as well to 0.96volts (throttle "closed")
NEW coolant temp sensor both gauge and temp sensor
Changed out the intake gaskets and exhaust header gaskets
New Fuel pump relay
New motor mounts
Did a vacuum test, no signs of exhaust blockage, motor has good vacuum
Compression test, cly were between 145-165psi, no cyl had zero compression
Replaced ign module on the dizzy
New clutch and clutch slave cly
New o2 sensor
Sprayed carb cleaner EVERYWHERE to check for vacuum leaks, found none
Seafoam the **** out of the intake used deep creep, then a bottle in the gas tank and a some in the crankcase (mixed with engine oil)
Misc things, rewired my lights and cb radio and amp. replaced e-brake cables, rear brakes, front brakes, new u-joints all around, driver side axle, fixed steering wheel looseness, new steering damper, balanced driveshaft, new tires (students slashed my old/new 33' mickies), made a headache rack, toolbox, body work and installed bullhorns.
Yea it's been a LONG ASS project. I'm sure I'm forgetting something. Anyhow my truck has been through Hades and back. I do not know what else it could be unless, maybe the new IAC is bad, or maybe I need a bigger heavy duty battery? or the alt upgrade (which I plan on doing anyhow). I'm trying to think of anything and everything right now.
I have VIDEO that I took of what it is doing, it is uploading to my youtube channel right now.
