Ok, today I cleaned the tube and replaced the EBP sensor. It was plugged. I swapped out IDM's and getting it rescanned today at 4pm. Going to do the buzz test again and this time ill film it. Hopefully its better. While swapping the IDM I found this connector and have no idea where it goes...any body know?

Could not for the life of me find its mate. It was stuffed up behind inner fender.

Sounds like your on the right track... the plug looks like abs to me also.. hard to tell. Let us know what happens

ghohouston · Jan 22, 2013

Have you not had an abs light on?

high desert stroke · Jan 22, 2013

no abs light. no codes for abs. I was thinking it was for some option that I dont have?

Have you checked the wires at the ipr? It could have a bad connection there or a bare spot in the wire. That could cause it to cut out like that.

Ok, just had codes pulled again. TPS code gone, re-cleared the ebps code since i did that today. Did the buzz test again after swapping the IDM. Same ****...injectors all sound the same but not very loud. Heres a video...in the video they sound louder than they actually were.

Everything looked good there. Still had its cover and red tape. If it cuts out again im pulling the VC's.

Thats good. Is the small nut on the ipr tight?

Um...i'm not sure. Kinda learning as I go. Didn't even know where the IDM was till today...lol

Im talking about the nut on left in picture. On my truck I had a issue where mine cut out, that was my issue. I had to tighten the nut up. Just something to check.

Your buzz test sounds normal

high desert stroke · Jan 22, 2013

Great! Thanks guys!

Be careful when you tighten that nut. It is a sheet metal nut and easy to strip out.

mandkole · Jan 23, 2013

yes the buzz was fine-- can you get a vid of when it acts up?

That is the connector for the front wheel ABS sensors, but your truck likely is only rear wheel abs so there is nothing to plug it into. Should be another similar on the PS.

Your BUZZ test sounds fine.

I would have leaned towards the "Tin Nut" on the IPR as well, but it could also be a loose connector or a bad coil on the IPR as well, you might try to ohm out the coil on the IPR, should be around 12 Ohms smooth, no spikes. Seems like there have been more coil related IPR issues recently probably due to aging or poor connections.
