I installed my injectors pushed them in good but am kind of figuring MAYBE they didnt seat right. Got the truck to start and let it run for 45-1 hour just idling. Ran it down the road 10 mins and it was missing and very low power. When going uphill I had the accelerator more than halfway down and was only going 30 and wouldnt accelerate until it dropped down to 25 then kicked into overdrive to get up to 30-35 mph. Hard shifts and really low power. Missing out under load.

 

Did u replace your valve cover gasket? Cause that's what it spuds like

 

yes new valve cover gaskets new injectors..flushed the gas tank and fuel lines then reprimed the system

 

Idm?

 

how would i know if its my idm or something else? is there any way to check it other than scanner or any other possibilities

 

Solution : It was the injectors.
So after you tear down your truck and remove the old injectors and prepare to start installing your new injectors, MAKE SURE you oil the orings on the injectors very good (this will help with easier installation). Push your injector straight down until you hear a snapping noise. I believe this noise is the copper ring making direct flush contact with the bottom of the injector sleeve. (Quick check) Make sure there are no old orings or copper rings in the injector sleeve before you go to insert the new injectors. If you do not hear that snap sound pull the injector and reseat it until you HEAR it seat properly. This will save you much trouble rather than putting your injectors in and finding out that they are not seated properly and you have fuel spraying into your valve cover and mixing with your oil. Take it from someone who made this mistake, it sucks! However, once you have your injectors in and seated correctly and the rest of the engine put back together be prepared for hard shifts and air in your lines. Before you start and run your truck change the fuel filter. It should take about 100 miles give or take some..to get the air out and for your tranny to act properly. If your truck loses power after 300 or so miles change your fuel filter again. I had to do this because of bad fuel. Even tho I drained the lines and the fuel tank, I believe there was still sediment. So, I ran the truck for awhile and it started to bog down again. Simple change of the filter was all it needed. I hope this helps anyone that has an injector issue. I know that in my search of figuring out what was wrong with my truck, I got really annoyed by the fact that people would post and post and post about their problems but never put a resolution to that problem.
