missing

[240sxbubbs]

Well I finally joined. I have lerked and learned a lot about my truck But finally had to join to ask my question.

details on my truck: 2001 f350, 6 speed, with 172k on miles.

This was like last week, I was driving home from the casino and the truck was running great with no problems what so ever. it rained the next morning and I thought to myself I should check my oil so I popped the hood that was full of water and it drained off normally how it should (onto the cowl) and the oil was good so I got in the truck and it fired right up, I waited about 5-10 mins for it to warm up then I took off and it had a horrible miss. I figured maybe it was because it was still cold so I let it warm up and it still had the horrible miss, It wouldnt build boost and was very under powered. Either way I took it back home and got on the website and did my research. Some people say it is the wiring harness under the valve covers and some say it could be the idm sensor. I thought before checking those I would try and start it, this is about 5 mins of it just resting and the truck was fine, I took off and by the end of the street the miss was back. I got the truck over to my mechanic and he tried an idm sensor off another truck and that didnt work and also checked the harness under the valve covers and said they were fine. At this point I am lost and I think my mechanic is lost also because he isnt answering my calls. Any ideas I can share with him on what may be wrong with the truck?


Thanks in advance.

You are going to have to get ahold of a good scanner to see what codes are stored.

I know my mechanic has a really good scanner. Like I said he hasnt picked up his phone so I couldnt tell you if there are any codes.

Well, until you can get ahold of him or the scanner you're just chasing the problem blind. I'm putting my money on the UVCH even though he said they were good. Curious how he checked them if he didn't have the valve covers off.

help me out here what is the "idm sensor"? i have heard of the idm itself getting water in it and going bad but have never heard of a sensor.

IDM Sensor = CPS

I think?

Im not 100 percent how he checked them. Lets say they were bad would letting it sit for 5 mins then it runs fine for a few hundred feet make sense?

Thanks for all the responses so far

No, but a bad CPS will do that. Does it start back up every time and then die after a few seconds?

Injector driver module is in the drivers fender , you have to remove the inner fender well . Take out the 2 10 mm bolts drop it down and see if it's full of water . It's a common problem .
