I have a 1990 Jeep Wrangler 2.5 and I have a problem with it bogging down like it's looking gas . I have replaced the map sensor the throttle position sensor and changed the spark plugs and wires. Fuel pump has 17psi pressure I even cut the catalytic converter off and replaced it with straight pipe and it's still bogging down. I tried seafoam and every fuel and injector cleaner you can buy. The only thing I haven't done was clean the injectors, that was going to be my next step or just replace them. I need help despritly. Any help would be appreciated thank you
