Our '92 Wrangler frequently sputters/hesitates for several miles when I start it up after rain. If it was a heavy rain, like last night in Kansas, it has trouble starting as well. This morning, I tried 10-15 times before it successfully turned over, then had to try again & give it a lot of gas before it would stay running. We thought it was the fuel line originally, but we've recently changed the fuel pump & hoses. And the fuel pump DID need changing.
This may be unrelated to the sputtering issue, but it also gets water on the floor, mostly the driver's side. When I turn a corner after rain, my feet get soaked. It has done that for as long as I can remember though. The sputtering/hesitating just started last year. If I remember right, it began when it got cold last year.
I've heard from someone that I should check the distributor cap, and I will do that. I also read something here about checking the hose beneath the battery for clogs. That was just pertaining to water on the floor though. I don't know if that would cause the Jeep not to start or to sputter while driving. Has anyone else experienced this issue? Or does anyone have other ideas?
