I power washed my CJ 2 weeks ago, trying to pinpoint a coolant leak, and nothing has been the same since.
The Jeep starts no problem and runs great when in driving, but as soon as I let off the gas it dies. It always starts back up after it dies. I have looked for vacuum leaks, and tracked down misplaced vac hoses and reconnected them back as close to the original hose diagram as possible. The PO had made several changes and rerouted wiring and hoses all over the place. I have sprayed B12 on the distributor and cleaned and dried both the distributor and cap. I have changed the spark plugs and wires. I have looked and I get two steady streams of fuel when the engine is off, until the bowl is full. I have adjusted the idle screw and nothing has fixed my issue.
Today I finally got it to start and idle for almost 15 minutes. Once it warmed up and was running ok I opened the throttle and as it came back down to idle, it began to run rough, and eventually tried to stall, unless I forced fuel. When I opened the throttle while it was running, I didn't see any fuel coming going into the carb, and instead got a sucking sound. I also noticed that the further the valve at the top of the carb opened up the rougher it idled, until eventually the valve stood strait up and it finally died.
I have only owned the Jeep for 6 weeks or so and it was running pretty well until I power washed it. It hasn't been on the road since. It is an '84 CJ7 with a 4.2L strait 6. I can add more pictures and/or details if needed. I am a novice mechanic at best, but I do have some decent help when needed. I bought this to help me learn and enjoy with while I worked on. Any help is appreciated.
have the same problem?
