Does the engine make full power if you floor it?
Ok I will give that a try I will let you know how it comes out after I get finished thanks for the help. I'll email you once I've tried it;
ok so got those two things replaced it did do the trick with the idle but now it seems to have problems when under load or accelerating it chugs really bad now and almost misfires. I installed both parts per instructions and unhooked the battery for about 2-3 minutes, then reconnected the battery cleaned out the throttle body before starting, went to start it but it took a few times to finally come alive. then once running it seems sluggish so I let it warm up to temp. after that it idles now which I'm very happy for. However now it has a sluggish stumble right as you try to put a load on it or accelerate to where it almost dies then comes back. Not sure as to why this would be happening. If you can shed any light on this it would help out tremendously.
Ok, it sounds like the timing may be a little behind. Try advancing the timing by turning the distributor slightly counter clockwise to advance it a bit.
Is it any better?
Ok thanks again I apperciate it! I'll see if I can't replace them after checking for leaks in the manifold area. I'll let you know how it all goes tomorrow I'm gonna go out and look everything over and will check back with you tomorrow if you don't mind.
Thanks again, Matt
Ok sorry wanted to give you a update its been a few days and I was off work for one of them. But here is where things are at with the truck. It will start but again now will not idle not sure as to why. The only things that have been done since we last talked is I did a complete tune up plugs, wires, cap and rotor did not replace the fuel filter as it was done about 2 months ago. After adjusting the timing advance several times with not too much luck. I ended up doing the full tune up, which did help with the smoother running a little under load but it still seems to have a small hesitation just before giving gas or load I cannot figure this out. If you can help me out with this I'd be willing to throw in another $20 or more. Thanks, Matt
Sorry for the delay in getting back to you.
Does the engine make full power if you punch it?
Ok, has the fuel pump ever been changed?
sorry about getting back to you in a timely manner had alot goin on here. I work at a guest ranch and this truck is one of the ranch vehicles; But no to my knowledge the fuel pump has never been replaced. Could that be a problem to what is going on? I looked for vacume leaks but its really difficult cause I know what they sound like and sometimes with the air cleaner off it sounds like a vacume leak but I've looked just about everywhere I can and do not see or hear the leak, enough to be able to find it. Thanks, Matt
No prob. I totally understand. The pump could be weak and thats why your getting "spotty" operation of the Engine in regards XXXXX XXXXX having power. If the Pump has never been changed it would be a good idea to start there.
Your very welcome. Let me know how it works out.
