Why would a 87 Toyota corolla run fine in park and neutral but stall in drive and reverse and Also changed fuel filter and plugs and air filter and oil and filter and PVC?

Answer 1

First of all, does this happen ALL the time? Or only when you are fighting with your significant other? My ex used to work for a car dealership, and when ever she and her (former) ex were fighting, she would "disable" his car with a little dirty mechanics trick: she would open the hood of the car, (and yes, it was a Toyota,) and would pull off the the distributor cap plug wires...the ones in the "first" and "last" posistion....she would then "switch" the posistion of these two wires, and re-connect them. End result? THE CAR WOULD START IN NEUTRAL, AND PARK, BUT WOULD "DIE" IN DRIVE OR REVERSE! Exactly as described in your "problem"! And since he was not mechanically inclined, he would take his car into (different) shops, and each one of them would "fix" his problem, at full cost, of course! So.......this might be a solution to your problem....hope it helps!
