Someone tried to steal my 90 GMC and broke the plastic steering column cover to gain access to the ignition mechanism on the left side of the steering column. A part of the starting mechanism was broken and now I can’t turn the key. The key cylinder doesn’t look damaged. I hear these vehicles are easy to steal with only a screwdriver to pull back on the mechanism and then the vehicle starts. Do you think that the damage to the mechanism is causing the key to not turn? I have a replacement kit for the mechanism and cover but not the ignition tumbler. Thank you for your help.

My check engine light is flashing, it has a miss awful throttle response, you can smell fuel from the exhaust and when the code is ran it shows it has a random misfire I have changed the spark plugs, plug wires and coil packs, could it be the spider injector or a crankshaft position sensor. I don’t want to keep throwing money at it hoping it will fix it. Please help

I am planning on removing the trans from this vechicle and I see there are two rubber plugs in the underside of the bell housing and underneath the plugs there are two what looks to be 10mm bolts. What are these bolts for or what do they hold in place. Should they be removed before I remove the other bolts and separate the trans and engine. Don’t want to bust something right from the get go.

I have a 03 GMG 2500hd 4×4 gas.About 4 months ago it lost power it said loss of engine power. I took it to a local place they replaced the throttle body and excel pedal sensor. A month later it did the same thing and I took it back and they said it as the excel pedal and replaced it. Well it did the engine power loss again and has a surge to it as I’m going down the road around 45 when I get on it, it runs great but around 45 it was surging. I had someone else do a tune up on it. The fuel line was stopped and they told me to take it to the dealership that the computer needed to be reprogrammed, so I did that yesterday. They reset whatever things and it ran great today until this evening and it did the engine power loss again and was doing the surging but this time it was idled up real high until I turned it off and started it up again. Someone told me that it cold be the wire to the throttle body. Can anyone give me some help on what it might be?

Usually it starts fine, and runs approx. 15-20 min., then starts missing and chugging when accelerating. If I slowly apply gas pedal it seems to catch then does accelerate. A little longer and it sputters, lurches. Then it doesn’t want to start. If I wait approx. 30 min. it starts again and go’s through same process.
