Cam synchronizer symptoms maybe?

Post by chevy454 » Mon Nov 26, 2018 9:34 pm

1997 Mercury Sable w/ sohc 3.0

Recently threw a tps and cam sensor code, i replaced both sensors, car ran fine a week or so and then the tps light came back on. On a cold start: for the first 5 secs to maybe first 30 seconds it has a miss, but then it suddenly quits. But now that its gotten colder, the miss is lasting longer and now it sounds like a lifter isn't pumping up for a bit...but after it gets thru this period all is well and the car runs fine. When I replaced the cam sensor the original sensor magnets came out in pieces. I haven't noticed the chirping everyone says will be present but I'm kind of stumped. Could it possibly be upper plenum gasket? Is it possible to get a bad tps sensor?
