I have a 1995 SE. It has the 3.1L. I am having an issue with the car running under a load. When you go to take off the car will bog down and feel like it is loosing power. Some times it will back fire and stall but not all the time. This problem began about two months ago. Just before the issue I had a head job done. The head gaskets blew and locked the motor. So I had new heads put on with all new gaskets. And now the problems began about two months afterwards. So far I have replaced the plugs, MAP sensor, oil pressure sending unit (due to leaking), O2 sensor (not sure which one the garage did not state) also replaced the CAT. The garage put in a universal weld in one. This issue is becoming irritating. I also took the EGR valve off and sprayed it down with Carb clean. Any help would be greatfull. Thank you.
