Most common problem would be tires are out a balance. Or, the tires are out of round ( meaning the tires have a hop to it; not completely round ).

Go to your local Autozone or Advanced Auto and they can check it for you. It is free as well! Can't beat that. Or you can buy an OBD2 scanner from them or online, and lookup the codes yourself. Those are about your only options. Hope I helped. If you have any more questions, post on my site. I will get back with you asap. codfanboys.comli.com

The plug gets power from the Cigarette Lighter 15A fuse in the underhood fusebox.

Most common fault is the steering rack ,it has valves inside and one of these could be faulty ,cannot see it being a ball joint as it would be stiff both ways but sometimes the bearing on top of the macpherson strut can get dry and corroed causing this problem ,what to do here is to put some engine oil where the nut is in the middle or the big washer on top of the leg under the bonnet and run car around for a few days and see it helps .When i service a vehicle i always put a drop of oil here as a matter of course to stop this sort of thing from happening .Its what comes from being a commercial vehicle fitter for many years and taught to use the grease gun and the oil can and if it moves lubricate it

check the fuse in the fuse compartment, make sure cable lead not broken, if lighter used frequently to heat up resistor, it ends up burning the wire, thus breaking off the back, replace if necessary.

did he replace the fuel filter at the same time, try that first , and be sure your timing is set correctly and that your plugs are getting good spark

rear centre of inlet manifold no just plug and play

It might be the drivers window switch. All power goes through there before the other window switches. But first check your fuses. Look in your owners manual to find location.

When you restart the car, the ecm will read sensors and reset itself to adapt to inputs it receives. Let the car idle for a few minutes, no gas petal at all, then drive it gently for a few minutes-then drive it normally. Because is has adaptive memory it will adjust for your driving techniques, and within 40 or 50 miles it will be completely set.

All Chevy and GMC trucks (pick-ups, Tahoes, Yukons, Suburbans etc.) during the years 2002-2004 had issues with the IPC (instrument panel clusters). The would be erratic, and sometimes stick at a certain speed and not move, or occasionally work then stop at a speed, then jump to the next speed. It is a common problem. Unfortunately the only fix is to replace the IPC, and have it reprogrammed at a dealership, or repair facility capable of programming. The IPC is actually a module, and communicates on the data line with other computers. The mileage will also need to be reprogrammed into the new IPC.

maybe your wheel speed sensor are malfunctioning.because your car have an interconection computer control the intere system

could be you belt or fluid low do you hear a whinying noise?

Check the fuse located underneath the drivers side steering wheel. Flip over the plastic fuse box cover lid and you will find a diagram that shows what fuse controls the seat. Replace that fuse with the same number fuse.

After opening the hood, look at the top of the headlight assy. You will see to short metal rods, one on eace side if the light. You just unclip the rods and lift them out. The headlight assy will pull forward, change the bulb (dont touch the bulb with your hands-use gloves) slide the assy back in till the holes line up. Reinstall the rods and snap them back in. Its about a 15 minute job.

They do have problems with the instrument clusters going nuts and not working, I've replaced a computer on one that would start and then die and had one with a bad ground wire causing weird problems. I love them. Fuel mileage? ummm.Bet just say tread lightly
