Alright heres the deal... I got a 93 coupe... my car seems to cut out or studder at about 2200 to about 3000rpm .. juss like a little drop out.. but i got gears and thats the rpm i ride in on the freeway... so its real annoying.. its only under load but it also does it when rpm or dropping down.. doesnt seam to matter where the pedal is at (rules out tps)... so here is the list of what i have done and pretty much ruled out..... i complete tune-up... new distributor... changed mass air.. and injectors... completly diffrent motor..ha.... all new gaskets... new throttle body.. egr spacer... i juss dont know what else to check its got to be a sensor or maybe the ecm... i just need a good direction... any help yall can give me would be awsome.. thanks.

Check the voltage at your TPS. You changed the TB, I doubt it's .95-.99...

THE AIR THERMACTOR IS YOUR AIR INJECTION I BELIEVE... (SMOG PUMP).. BUT.. I TRIED CHANGING THE TPS AND THE PROBLEM IS STILL THERE.. NO CHANGE STILL SPUTTERS AT THE SAME SPOT... IM GONNA TRY UN PLUGGING THE MAP, AND PUTTIN MY IGNITION BOX TO STOCK AND SEE IF ANYTHING CHANGES...

HOW DOES MY COMPUTER TELL IF THE CATS ARE WORKING IF IT DOESNT HAVE ANY POST O2 SENSORS.... WELL I HAD THE PROBLEM WITH TWO DIFFRENT MOTORS... IT HAS TO BE IN THE WIRING SOMEWHERE.. SENSORS... OR MY IGNITION OR SOMETHING... I DONT THINK ITS MECHANICAL....
