Luging down I have a 95 wrangler and it bogs down when on the road and cuts out as if it is flooded. I have replaced the crank sensor, speed sensor, fuel filter, and the fuel pump. All I have left is the O2 sensor that I know of any ideas?

check the fuel pressure and the float level as it may be too low or trying to flood the engine . check for vacuum leaks in all hoses.. Check that the carby is tight on the manifold.

Similar problem due to wiring on ASD (automatic shutdown relay) not connected tight to terminals on underside (fuse box under hood). I encountered this problem repeatedly after a mechanic (national chain) kept removing this wire for some reason (eventually causing computer to fry). Also related problem misfiring/backfiring/bogging down under certain driving conditions I traced to the battery sliding into computer wiring harness and disrupting sensor input/output signals. Placed 1" spacer on rear clamp to push battery forward, which cured this problem.

if it is driveable, but seems to cut out, and bog down at sporatic times, and speeds then odds are it's the distributor. (the electical flow is intermittent when it should be constant) if it only happens at higher rpm then it could be the cam position or crank position sensor

Have you checked the cam sensor? Also does that vehicle have a "throttle position sensor"? Some cars use both MAP and MAF sensors, not sure about your particular vehicle but if it is one of those, cleaning the MAF wouldn't hurt. Good luck.

Replace the catalyst convertor. When a convertor goes bad, the guts of it break apart and end up clogging the exit port. One of its functions is to remove toxins from the air. Helps the emission system to run rich or lean gas exhaust.

Check the fuel pressure because it sounds like you have a weak fuel pump.You should have 41-47 psi with the key on and engine off.

I had the same problem with my 89 grand am it was caused by a faulty crank position sensor. Initially it would cut out when accelerating and eventually wouldn't start at all, replaced the sensor runs great again.

Find the EGR valve on the intake and locate the vacuum hose that is connected to it. Start the engine cold and as it warms up, pull the hose off and if it idles and drives fine, the EGR valve is bad and needs to be replaced. Please rate me on this answer.

I had a problem with a fuel return line that caused my 95 YJ to do the same thing. It was getting flooded after a few short miles, and would not start for a while. You can buy a fuel pressure gauge and check the fuel pressure, if the pressure is to high that might be your problem. I took my fuel return line off after checking the pressure and tried to blow thru the line with my mouth and could not. After dropping the fuel tank I discoverd that my skid plate was dented in, causing the bottom of my fuel cell to be pushed up and the end of the fuel return line (in side the tank) to be blocked. Good Luck, and if that ends up being the problem you may want to replace your spark plugs, they may have been fowled because of the excess fuel.

have you checked fuel pressure regulator.hopefully this helps
