Do your needles bounce? Do you have a tackometer? Does if fell like the engine surges or just the movement? May be your trans, may be something else. My trans am had the electriconic ignition switch (on steering colomn-and same for chevy trucks) go out and the engine surged with ALL neeles bouncing. That was not all that common, nor uncommon. You need to determin if it is the engine or trans before going forward, if it was the ignition however then it would not have started back up after you shut it off, could be fuel, air filter or many other things though. Drive down the raod and let me know if you think it is the engine and I will send you a list of more things to check. Check your transmission fluid level before driving

YES, my gas gage has been jumping around for the last few months I haven't noticed any others though. No I don't have a tackometer. I'll check for the electriconic ignition switch when I get home tonight. It does start easily and aslo goes into gear with no problem. I was thinking it might be dirty fuel since I let it go to complete empty before adding more fuel especially since the gage hasn't been working properly. Oh I was also asked it I ever serviced the transmission before and the answer is no we bought the truck with 60K miles we haven't had a major tune-up yet and were at 115K so I know we definetly need to do that.

I do not think it is your electronic ignition, more that likely your fuel. Change that filter and get a tune up. You need that tune up even if that is not the problem

Getting a K&N air filter, a new fuel filter, plugs and wires, oil change, and so on will be a great idea even if it does not solve the problem. Ther would be no money wasted. Here is a list of things to check. Transmission (fluid/filter); air leaks at intake; incorrect timing; faulty spark plugs; air filter; spark timing control system; faulty ignition; clogged catylitic converter; brakes binding; fuel flter; EGR system; use of bad fuel; low or uneven cylinder compression. Hey. You can take it to Advanced and have them hook it up to their computer and look for codes

I am not sure that that jerking is the trans, but if after everything you find out the trans is the problem then you have a desicion to make. After talking to several gear heads I found that many believe that changing the trans filter and fluid is only good for preventitive maintenance. Some say that if a transmission is going out that changing the filter and fluid will not help and it may make matters worse. I was told that if you have chips of metal floating around and you drain the fluid and change the filter then those chips will go eleswhere and get into more places. I have personaly seen changing that fluid and filter sovle the problem and I have seen changing those things do nothing and tha trans go completely out after. If you do have trans problems then you may want to try the filter, or do one of two other things. 1 drive it till it quites, it may last a year, but could also go out at a bad time. 2 have it rebuilt ASAP. The sooner it is rebuilt the cheaper it MAY be. A basic rebuild is around $1,400 with or without the torque converter which runs around $300. But if you continue to drive it that may cause pumps and bands to go out shooting the price up. If you have to have a total rebuild it may be over $2,000 easy. Just do everything you can to that engine. Your problem really does sound like fuel, maybe pump, filter or relay. Wait. You said 4 whell drive? May trans estimates are way off. Add a few hundred to each price. AMCO will give you good estimates and you can take those to a few places to get the best price and warrenty. If you take good care of your engine you can see it to 200k miles, if you take great care of tht v8 you will see more.
