My truck won't run if the map sensor is plugged in but if I unplug it it runs prefect. If i plug it in when it's running it will go dead like it runs out of gas And won't start back until I unplug it. No check engine lights. Also I noticed the oil pressure gauge started going out around the same time

sometimes when I start it up it idles rough and if given gas it acts as if it is getting way to much fuel or not enough, and continues to happen when I put it in gear; then engine light starts to blink, and can smell gas. It stops, but I am concerned and want to fix it. I like to work on my own stuff. please respond.

I am concerned with getting better gas mileage and doinf light work with my truck

This happens almost every time I use my brakes.


I jumped the low pressure switch and compressor runs fine so I replaced switch yesterday. Today same bullshit are these switch known to fail a lot?

The gear catches, but when I accelerate backwards there is a grinding sound an no motion, is it a solenoid problem or is it something entirely different?

Having a little difficulty putting into park. Once I can get it in park, the key does not want to come out. If I leave it in, it is not completely turned off and it drains the battery. Acts like it is not recognizing that it is in park. Not sure what the root problem is???

keep adding power steering fluid when gets empty or when makes sound when turning and or driving.

6.0 manual five speed. Only after the truck has warmed up, it will cut out while at lower rpm's. Idles fine and runs great when higher. Mainly notice when climbing hills etc but will do it at any point when they are low and you go to accelerate. Occasionally there will be a backfire following this. Possible that the catalytic converter has been removed when dual exhaust was installed. Bought this thing recently so if this started after I would not know.

My mechanic feels since the power steering pump is only a year old, it is probably the steering/brake assist unit. I assume that is the hydro boost I have seen in searching. Does this seem to be a reasonable guess? It is not leaking and the belt/tensioner/ pump pulley all seem to be fine. Any tips on swap out and bleeding if I do replace it?

I replaced the fuel level sensor and it appeared to fix the issue at fist. Now I run out of gas when the gauge reads half a tank. I know GM had issues with there gauge clusters but not really sure where to start now ? Any ideas ?
