Check engine light. And no power

[bdpprocessors]

Lastnight i was leaving work and my truck all the sudden started running horribly. Sounded like a few cyl werent running. Well it went away so i shut my truck off and looked under the hood. Wighled all the injector harmess conectors and. Continued on my way without a problem. Today on my way to work it happened again. But only goes away randomly for about 30 seconds. Only thing i have done to the truck recently is put on a new exhaust ( 5 days ago) and put a new fuel filter on ( two days ago).

Any ideas or tips would be great as i would like drive back to my parents house tonight when i get off work for the holidays.

This truck has always ran great. Never any major problems. Now its running horribly and im stumped as to why.

My 96' f250 acts like it is only running on 4 cylinders. When it first starts, sound good for about 2 seconds then goes low power/rpm's. Ran fine last time I drove it about a month ago.

Check your valve cover gasket and harnesses inside and out then do a check on the IDM.
I had to replace the gasket, harnesses and IDM then I found out two injectors went out so I replaced all 8

Thanks, I have been reading about the harness, but what and where is the IDM?

[97workhorse]

Injector driver module located near the driver side firewall bolted on the side its got a big wiring harness connected to it. Look on eBay for one there's a online distributor that sells them for 136 you also have a IDM110(110 volts) you can get a 120 for the same price and get more power. My recommendation first before you start replacing things like I did is go to Ford and get a diagnostic for all there equipment then order the parts yourself. Oreillys has the gasket and harness for 140 w lifetime warranty. My IDM also has a lifetime. And if you need injectors buy brand new alliants you'll be glad you did and if you plan on keeping the truck replace all of them.

You need to plug into it!! get the fault code or codes but i agree with 97 workhorse,unplug your pass-thru connectors and see if their melted. if you do have to replace put dielectric grease at pass-thru connects and will not have this problem for a very long time,the two outer wires in the pass-thru are for the glow plugs and pull alot of amps creating alot of heat which melts the connector. you can purchase the harness ends in pieces no reason to replace the engine harness. good luck!
