    Truck idles rough at start up only.

    I think I'm pretty much over this truck. I'm not sure if I can post a for sale here but if I can I probably will here soon. Somebody will hopefully get it going and get a good deal.

    Truck idles rough at start up only.

    I have put so much time and effort into this truck. New rust free box, all new rear suspension, brakes, brake lines, cab mounts, cab corners, rocker panels etc... 3 coats of SPI epoxy primer on it and the frame. I might just put it up for sale.

    I got it back and it's still doing the exact same thing. Rough idle on start up then runs fine on the road, drove it home from his shop 30 miles and it did great. A week later took a turn for the worst died in my driveway doing its thing again sounds like it's running on 2 cylinders. I told...

    I will let him know that he may already have pinched a fuel line. He likes it when I arm chair it from home. Good stuff thank you.

    Truck idles rough at start up only.

    I just talked to my mechanic. He said it's the fuel pump, fuel pressure regulator on the TBI and the car quest distributors are junk. So he's going to replace them and I will get a refund on the distributor. The fuel pump is from LMC 2 years old. 9 pounds of pressure. He said LMC stuff is...

    How much did it cost? And what does it tell you? I have replaced literally half of this truck in new parts. Still not right.

    I got the tamper plug out. Now I'm going tamper with the idle. We will see.

    Why would you do that? Do they actually call it a tamper plug? Erik said not to mess with it and schurkey would agree. They said I need a scan tool. Ive pretty much tampered this truck to death might as well get this tamper plug out and see what happens, thanks for the Info I appreciate it.

    Truck idles rough at start up only.

    Ok if you have scan tool you like could you please recommend one. Everything I have been able to find on setting base idle is pretty much the same. Get the truck warmed up. Jump the 2 terminals, turn the key on, wait 30 seconds then unplug IAC. Start the truck up with terminals still jumped...

    Truck idles rough at start up only.

    So I started it up this morning and it's still rough idle at a cold start. Took it about 5 to 10 minutes to really come out it and be drivable. After that it ran great drove around for about a hour idle is a little low so I went out to set the base idle and there is a plug in front of the torx...

    Yeah I don't have a scan tool I used a paper clip. Vacuum line is new. Bought yet another IAC today and that solved the idle problem. IAC must have been from China. Have yet to drive it but so far so good.

    Replaced MAP sensor and adjusted timing to make sure it was good. It's still ****** up like Polio.

    Truck idles rough at start up only.

    I took EGR valve off and capped the intake with a plate I made and sealed it up, did away with the EGR solenoid and capped that vacuum line. Still runs the same, rough idle at start up, high idle around 1500 rpm but drives fine. Did that paper clip trick to get codes and the only one that came...

    I'm not good with a laptop. I just recently had the fuel pressure checked and it was good. It's very close to the point I may just put a Carb on it.

    I think you are exactly right I am going to replace all the vacuum lines next week. And map sensor and EGR solenoid. If that doesn't do it I'm not sure what else I can do. Thanks for the help.

    Another member suggested it, it was cheap and I have replaced everything else on the truck might as well keep going now.
