Hi moses call me stupid my jeep is a 2001 sorry it runs good when I put the sea foam in the tank but if I dont it dies at a stop light . I already replaced the coil rail plugs # cyl injector it is the original engine I thought I would replace the tps sensor, the co2 sensors and see what that does if that dont fix it maybe the fuel pump? thanks Jerry

ok thanks moses also this engine has no distributor cap what is this called I have never seen this before as for the original problem it act like it is starving for fuel to me I thought of replacing the fuel pump do you think it would be a good Idea? thanks Jerry

ok 1991 jeep wrangler 4.0 6 cyl. problem Jeep runs great (105.000) miles when I have sea foam in the tank,have been using premium without ethanol but every now and then it runs rough till i put the sea foam in it check engine light said #1 cyl misfire so new plugs coil rail,new injector # 1 cyl then it ran fine for about 1 month then same problem . what I cant figure out is why does it run good when I put sea foam in the tank ? I dont think it is suppose to run on seafoam alone thanks for any help, even the dealership is baffled
