Idle Problem on 1997 TJ Sports
1997 Jeep Wrangler Sports 4.0L
(I do have jeep build if needed)
Well, I was out wheelin about a week ago and I had to go threw a pretty big puddle, It was deep enough to cover 3/4 of my rims (stock suspension), but not my engine, had to have a little speed so some water went on top of the hood, and a lil in the engine compartment. After I got out of the puddle I did open my hood and inspected to make sure everything was okay & secured. I also inspected the intake well to make sure a lot of water didn't get inside, I have a K&N Air intake installed.
Ever since I have done this my jeep has intermittently been idling weird. When I start up it'll idle normal, after engine is warm and stop at a light, it'll be idling around 1300-1500rpm, then if I step on the gas and spike it real close to 3000rpm, the idle will return to normal (a little below 1000rpm looks like 600-700rpm).
I have inspected vacuum hoses and check engine light is off.
Thank for your help Jeepers!
