Hello, I have a problem with my 95 wrangler. It shakes when it is in idle also in first gear (automatic trans). I had the engine replaced hoping it would solve this problem but it still exists just not as bad, before the engine replacement it would shake to the point that it would shut off. Almost everything is new inside, engine, thermostat, water pump, distributor, wires and plugs, fuel pump and injectors, o2 sensor, map sensor, pretty much all the sensors; the only thing that hasn't been replaced in it is the computer.
The mechanic who installed the new motor saw the problem on the 500 mile check up and then ran tests and said that there is no error that is coming up on any of the testing equipment. His advice was to run it, the jeep, until the problem gets bad enough and hopefully they can catch the error on a diagnostic machine. Has anyone had this problem or similar problem? It also seems to get worse after it has been driven for a while. The first start up and drive is fine but after 20 minutes or multiple turn offs and turn on (going to a store and turning it off then hoping back in and cranking the engine) seems to make the shaking worse. At speed, 30 plus mph, it runs smooth but sometimes I feel it shake as if gas is not being sent into the engine.
Any advice would be appreciated
Thanks.
