Ok I bought me a equus 3145 obd1 scan tool and it gave me the following codes:
116- engine coolant temp higher or lower than expected
122- throttle position sensor below minimum voltage
336- egr sensor circuit voltage higher than expected
542- fuel pump secondary circuit fault, I did like you said I checked made sure all plugs are getting fire they are changed oil, would one of these codes be causing it to do that
