Lame Mechanic

[Guest]

--------------------------------------------------------------------------------
I had a Fiero which always had some kind of ignition glitch. Since new thr tach would jump and cause the engine to buck. While new and under warranty the dealer replaced the TPS several times but that never cured the problem. After about 14yrs of use the problem got considerably worse. I changed cap ,rotor , plugs, wires and coil. Check engine code always reported O2 sensor.
I took the vehicle to an auto-electric shop and had the tech test the ignition system. He found no problem.
Finally I took the car to a local shop. These lamers used an hours labor to tell me that they needed to change the O2 sensor. The mechanic was offended when I questioned his ability to diagnos the problem. i mentioned that the problem was evident when the engine was cold or ran in closed loop and that the O2 sensor output was not valid till the temp was high enough.
The best advice he gave me was this: "if you know so much fix it yourself".
I did that..... just replaced the entire distributor.
...that was the cure!
..after looking and disassembling the old distributor I found a broken lead on a hall effect transistor.
It was just fractured and was the problem from new.

Sorry to hear of your troubles finding a reliable shop/tech. Please understand a few bad apples does not spoil the barrel . Ask friends,neighbors, co-workers for referrals. If the shop has one ask to speak with the foreman /mngr. find out before theres a large bill what you will get for your money . tell him things that have already been done.He may have to repeat some tests.Ask if he could take the time to explain the work done. A good shop will do this .Mine did. BTW ,Good work on finding problem.
