This whole problem started 3 weeks ago. I started my truck and let it idle for about 5 minuets and took off down the road. About 1-2 min later when I went to put the clutch in, it stalled as it went down to idle. Tried 4-5 times to start it, and it ran like normal. Drove it another 1-2 min and it stalled again when I put the clutch in. Started on either the first or second try, and I tried to limp it back to work. Pulled into work, got out letting it idle, checked it over, it seemed fine. Turned it off, checked oil, coolant, etc, nothing seemed wrong. Pull out of my stall at work, and it stalls again with clutch in. Starts right back up and I drive the whole way home with out a problem. I replace the fuel pump, because its under warranty, and It runs fine for three weeks, with just a little bit of a high idle every now and then (1000 rpm) and sometimes its slow to come back down to normal idle (7-800 rpm). I figure I'll look at it next chance I get and drive it daily. This brings me to saturday, I finally get around to trying to find the reason for my idle, and I find a vacuum line that has melted quite a bit on the exhaust. Replace the whole line from the manifold to the air box. Start it up, and it runs like sh*t. Exhaust sounds like this ...*..*..*.*...*.*...* at idle, kind of like its misfiring. Idle won't come down from 1000 rpm. If you rev it, the exhaust sounds fine and it doesn't seem to have lost much, if any, power. Still drivable around the block, and It hasn't stalled since the initial problem three weeks ago. Today I wen't out to check it and it was running the same. had a miss and would not go under 1000 rpm. when reved, it would be very slow to come down. Exhaust had a hint of an eggy smell to it as well.
Things I have done so far:
Checked for vacuum leaks in all hoses
replaced exhaust side plug wires and checked plugs (looked all the same)
had the coil or whatever its called on a DIS checked, and it passed
fuel pump
checked resistance on the IAC, passed and idle drops to 5-600 when unplugged. cleaned as well
MAF is new as of a year ago, unplugging it doesn't help
Things I will be doing:
TPS voltage test
Compression/leak down test
What can I check and rule out on this? Anyone have any suggestions? Ive done a ton of looking on this and no one ever comes back with an answer, and It could be tons of different things from what I've read. I don't have a lot of money to throw at this in parts, and I just fixed the head 1,500 miles ago. Since its my daily, I need it working asap or I will have to get rid of the old girl.
