I bought a 98 jeep wrangler with a 350 in it and it ran good for a while. I replaced the carb for a brand new edelbrock thunder series off-road carb. It ran fine for a month and now I'm having problems. That's the basic back story but here's the problem I'm having now. It starts and runs fine first thing in the morning until it gets up to normal running temp which is about 190 degrees. Even at that temp it runs good upp to about 40 mph the. It starts to bog down. I have replaced all plugs and wires distributor cap rotor and coil. New fuel pump and for what it's worth a pcv valve and all the vacuum lines that I know of. Oh and the fuel filter. I have know idea what to do now. Please help. Anything is appreciated. I'm not much of a mechanic just learning as I go.
