I have a 97 4.0 with intake that 108,000 miles. It has about 1 hr of ride time on the last oil change. I pulled it in favor of a 5.3. There are no issue with the motor and comes with the computer that's for an auto trans.
YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE DUCT TAPE.
IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.
