i have a 1992 convertible, 2.3, and im having all kinds of problems with it right now. its idling very low and sometimes stalling out, engine shakes, sounds terrible, when i hold the brake to shift into drive, park, etc. ive been going thru alot of gas, barely gettin 10-12 miles per gallon. i have changed the o2 sensor, spark plugs, plug wires, mass airflow sensor, pcv valve, fuel filter, egr valve and the sensor that attaches to it, among other things, thats just all i can remember at the moment. its still runnin terrible, i can barely get to 55 mph and to get to that takes forever. ive had the transmission checked, i just had a new one put on less than 4 yrs ago and everything checks out. i had all new exhaust pipes, muffler, everything except the catalytic converter, put on less than 6 months ago. its almost like it isnt getting the fuel it needs to go. does anyone have any ideas what this might be?

Have you checked the fuel pump or (I am not sure if the the 2.3 has one) the IAC?

we tested the fuel pump, it shows the pressure as 32, i had read somewhere it was supposed to be around 39-42...would that be enough to make it run this way? i dont know what the iac is???

Does it have a MAF?. When they go bad they will cause the car to run like that. Also check for vacuum leaks.
