Just recently acquired this `88 trooper from a salvage yard. Perfect interior, straight as an arrow body w/no rust, clear coat gone but the prob is it obviously sat awhile before being hauled away. Replaced the fuel pump (reason for being junked) and started her up. Great oil pressure but there is a ticking that sounds almost like an exhaust leak. The engine has a slight miss to it. Could it be an injector sticking? I`m new to the world of fuel injection. Gimme a carb. Got other questions but one thing at the time.
