When this was occuring putting it in gear would usually kill the engine since it was running very abnormal. I popped on a new fuel filter (recently bought) while stuck on the gravel road. Later after sitting a bit I was able to get it going. Drove home and later went out for a test drive it worked good , BUT while cruising at about 55mph I punch it and the transmission shilfted down as normal and then you could hear and feel the engine was stuttering and the speed stalled at about 60 mph so I let off and re-tried with the same negative result. Later while at low rev the engine started running rough again. The engine chk light is not on! Anyone have any advice? P.S. I did inspect the battery positive cable connector to the fuse block but only at the battery end, I want to inspect the other end of the cable where it terminates under the hood fuse block. YOu know just to look for corrosion, probably not the issue.

Lastly, would it be wise to go to a reputable but smaller (non dealer) shop to try to save some $ or is a dealer the way to go if I can';t fix this my self?

Like any business there are goods ones & unfortunately a few bads one. If there isn't a regular shop you use, you can ask around, friends, family & neighbors. See who they like and don't and why. It wouldn't hurt to have the codes read just to see if anything is stored, sometimes ones will set with no light but I misread your post. I thought you said the light did come on. I see now where it didn't...   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
