Hello,
I just purchased a clean, well maintained 1991 Trooper with the 4-cylinder & 5-speed, 175,000 miles. It idles and cruises fine. When pushed hard or cruising up hill, it surges and misses. I have not checked anything yet, but will do an ignition timing check. The previous owner reported he did change the cap, wires and plugs somewhat recently. It feels like a fuel delivery problem. Is there an adjustment for the injection system, or a way to service it? I do get a noticeable smell of rubber burning when it warms up. Is there a hose that could have dropped down, melted and is now leaking vacuum?
Additionally, the dome light does not work. There is no power at the unit's manual switch, nor is there ground continuity to the door switch. The fuse block indicates the cabin light's power is on the same fuse circuit as the horn and the horn works. Is there a simple connection that may be loose or corroded from moisture? Is there another switch that activates/deactivates it , like the headlight switch on many vehicles?
Thanks for your insight!
Sincerely,
Rick
