Suggest a professional mechanic w/ Dealer-level scan tool thoroughly vet it for you, OBDII live scans, highway driving test, get all stored & current Fault Codes. Scotty recently scanned a Dodge Durango that threw 23 Codes. That way you're not throwing more parts at it, just by guessing-- you'll have the data to back up your diagnostics. Did you change plug wires? Did you install OEM genuine ACDelco parts?
