1999 GMC Yukon V8 Four Wheel Drive Automatic 80,000 miles
when I am pulling my trailer with or without my atv's, the front end shakes pretty bad. The first time it did this, the check engine light came on, so I took it to a GM dealer. They said it needed a complete tuneup. They replaced spark plugs, distributor cap, rotor, plug wires, flushed transmission, and all other routine checks to sell their $800 tuneup. As soon as I hooked up the trailer again, I had the same problem, but the check engine light no longer comes on. I don't know where to start, or even what the problem may be, and I'm trying to avoid taking it back for them to charge me an arm and a leg. Any suggestions?
have the same problem?
