hmm, when it does start when its cold does it skip or lope or run rough for a second?

 

It sure does. Sometimes it takes a few miles to start running smooth. I have thought about pulling the valve covers and doing a compression test.

 

now see most lopes on startup that i have encountered have been glow plug issue's because of cold cylinders or the ebp valve. have you changed the icp sensor or the cam sensor?

 

I have changed the IPR the ICP sensor and the cam sensor. I also cleaned the pipe that feeds the back pressure sensor and at one time had the EBP valve harness disconnected. I guess when I find out what is really wrong it will seem simple like "how could I have missed that" but for now it feels like beating my head against the wall.

 

throttle pedal malfunction? causes a dead pedal at times and a rough running condition

 

It isn't having any throttle response problems. The only other thing that has happened is with the rain we had lately is when going down the road it will act like it is dead for a second and buck one time and then it is ok for a while. It has only done that when it is raining.

 

right that's what a bad gas pedal on these would do, eventually it would get worse and worse. its just a thought though, i really dont see how it would effect the starting but im only 17 i dont know too too much about these haha

maybe something with the hpop?

 

That'd be an issue unrelated to starting.

Just curious, how long since the oil has been changed?

And I hate to say it, but I'm pretty sure the injectors are gettin weak. The poppets are allowin cold heavy oil to push past. It'll still pass tests, and won't throw codes, but it'll do what you're sayin...

It has been about 4000 miles but it did the same thing from the day I put the used engine in with new oil and the old engine did it also. I used the injectors from the old engine but I did change the o-rings while they were out so I guess that is possible. I hope not since until the spring when the diving industry picks up and business gets better there is no money to spend on a set. We will just have to plug the block heater in until then.

 

If you don't wanna keep the block heater plugged in and run up the light bill, there are heating elements that replace the dip stick. I'd think they'd use less electricity than the block heater, and they'd keep the oil warm. Since the issue is caused by cold oil.
