CE code 214 engine bucking under accelleration, only when the car is hot

[dcssho]

I have an ongoing issue with poor drivability only whent the car is hot/warmed up. My car is a 1994 MTX. It will buck violently when accellerating and idle rough. The tach never bounces or changes when this happens. Runs perfectly fine when the engine is cold. I have already replaced the cam sensor, crank sensor (and all 60K parts), plugs and wires, coil and DIS module. Still does it. I am frustrated.
Recently I read somewhere to unplug the cam sensor and drive it. I did this just today after I had the car acting up and fully hot/warmed up. Stopped, popped off the cam sensor connection, started it after a few attempts and it drove just fine the next hour. My question now is what have I determined? Is the sensor I got bad, or is there a problem with my wiring or the plug to the sensor?
Not sure where to go from here and any help or suggestions you may have would be greatly appreciated. :thankyou:

it could be either the cam sensor is bad, or the wiring has a bad wire and/or connection.

how much oil is leaking from that cam seal? hot oil on those sensors makes them very unhappy, and since your issue is with a warm engine, my suspicion is that the cam seal leaks badly enough to mess up the cam sensor once the oil is hot.

I have recently gone through this same issue with my Gen 1. When my car wouldn't start one night it turned out to be a loose battery connection. After cleaning and retightning the terminal the stutter I had been encountering has not returned. Worth a look. Maybe poor connection was causing a voltage issue with the cam sensor????

No leak from the seal. Verified when I changed the sensor last fall and when I did the timing belt, h2o pump, cps, cam seals etc. last weekend. I thought the cps would solve the problem but it did not. I will check the plug connection to the cam sensor this weekend, and try to throw another sensor in there as well, maybe I got a bad new one.

I also have planned new battery cables as well. I will install this weekend and see if that does anything.

Thanks for the replies

After all my repairs it turns out the cam sensor was bad from the start even though it was new. I finally figured it out by unplugging the sensor after the car was hot and acting up. The car ran perfect after disconnecting.... Replaced with a new sensor and the car runs perfect now. Guess I should have done that right away before repairing other parts. At least now I have done almost all the needed maintenace items on the SHO.
