Engine Mechanical problem
1988 Jeep Cherokee 4 cyl Four Wheel Drive Manual 240000 miles
I just installed a new exhaust manifold and a new o2 sensor. When I started it the idle speed was very high (perhaps 2000 or more rpm). I let it run to operating temp but the idle speed did not and does not slow down. This is a fuel injected throttle body.
I've checked the vacuum hoses, replaced one.
Disconnected the some of the sensors near the carborator with no change.
I can't find a schematic showing the sensor connections to check if I have them all connected correctly.
have the same problem?
