Please help going crazy

OK I own a 1996 Ford F-250 7.3 my problem is that at low RPM‘s going up a hill maintaining semi low rpm’s under 2000 the truck chugs just about every time motor is under a little load it chugs high rpms seem fine I don’t know I’m new to the truck checked fuel pressure at low rpms it’s I think 80psi then floored the lowest I seen was around 45psi tacking little over 3000 rpms. Also replace valve cover gasket on passenger side because glow plug connector was burnt up but I had the problem before that I checked turbo, pulled injectors plugs ( with valve cover on) I don’t know if this is relevant But when I first got the truckAnd it did not even have enough power to run over a curb Oh turbo gauge floaters a little bit at high rpm’s it makes me feel like a injector ain’t working rightCan someone please help me I’m going insane

Re: Please help going crazy

You checked your fuel pressure under WOT...45 lbs should be good.

For low power, check the MAP hose, MAP sensor and make sure the turbo boots are on tight.

How many miles are on the truck?

you might wanna rewrite your issues...I had to read it several times and I am still not sure what is going on with the "chugs" maybe put in specific RPM it a manual shift and automatic transmission?

Can u do a buzz test to check your injectors?
