Question about 1993 Ford Probe
I have a 1993 Ford Probe GT 5 speed manual. While driving the car will jump down to 0 RPM and will slow the car but the engine will still be running (this does not happen when it's idling). Usually if I give it some gas while it's coasting it will eventually start going again and the RPM's will jump back up. Also recently failed emissions. Any ideas what is going on?
The tach suddenly falling to zero while driving is a classic symptom of the notorious distributor failure in the 1993-94 Probe GTs. There is a part in the distributor called the ignitor that is failing because they were not made to withstand the high heat conditions of the Probe GT engine compartment. Unfortunately, Ford does not sell ignitors and they charge an insane price for a new distributor.
The easiest solution is to buy a replacement disty. The problem is that many of the rebuilt distys sold by auto parts stores also have ignitors that will soon fail. There is an outfit with an eBay store called the Distributor King that sells replacement distys with upgraded ignitors. The distys they sell are manufactured by Richporter Technology and the model that works on a '93 PGT is number MZ25 ( thats the manufacturer's number, not Distributor King's). You might try checking the price on eBay then google the part number and see if you can find it at a better price elsewhere. There are also other vendors on eBay that say they sell the same identical disty for less than Distributor King. You could email them and ask who makes their distys.
If you are handy and have some time on your hands there is a way to jury rig a replacement for the ignitor for about $20. There is a detailed discussion of that here.
