Back again this year, I now have 340,000 miles on the 93 Probe GT. All I can say it's the best car. No problems this year. "pokey"
I cannot really condone the "use any old oil" comment!
Mazda engines are made to very tight tolerances, so use a high quality synthetic oil (I use 5w-50 mobil 1) and I change it every 5000 km. Noisy lifters can be cured by a high quality engine flush like engine detox by Liqui Moly, a German company, it fixed my rocker noise permanently.
I also use K and N filters and NGK iridium plugs on my 1996 GT Probe. The only hiccup was a dodgy distributor, (made by Mitsubishi for MX6 and Probe v6). Heat kills them long term, and I now have an oil leak, probably the front crank seal, it's not major at this point, so I will keep an eye on it, and see if it worsens.
I am a retired mechanic, and I find the Probe a great car.
Sounds like a transmission problem, could be a sensor or lots of other things. That recently happened to me in my Impala and I needed another transmission. Try to put transmission fluid in it, and have a mechanic look at it.
Bought an 89 Ford Probe (auto) last year for $500 when my newer Sunfire was stolen. Never bothered to upgrade the Probe to a newer car after, as I found it to be a robust and reliable car, except for a host of electronics issues with both the on-board computer and digital dash, and with the manual/auto shift warning light constantly blinking on 'Man Shift' when the manual shift function has never worked since the day I bought it.
It never really bothered me, nor did the day when the on-board computer 'died' and never came back on. Not even when the speedometer would not function until the car was warm enough.
Where it bothered me, was when it began to first drop back into a lower gear uninvited, and eventually shift to neutral and stay that way (with me losing speed and revving the tach up into the 6000rpm territory) until I pull over (or hit a stop light) and kill the engine for at least 10 seconds, and then restart.
Doing this 'resets' the tranny, and it will shift properly again for a couple of minutes, but then repeats the same pattern. First stuck in 1 gear, then shifting and staying in neutral until resetting. Sometimes it will last for a few minutes or a few seconds, but usually I get get to a red light or a breakdown lane where I can re-set the engine and go again.
This seems more of an electronic issue rather than a shot tranny, as the transaxle CAN shift properly, but I have no idea what to do or how this can be addressed (cheaply!) I'm not making the money I used to.
Has anyone else experienced this? I seem to be alone so far.
I have a 93 GT. Had the same problem; there is a switch in the rear driver's side panel. It's a fuel cut out switch. Make sure it's pushed in, and if that doesn't work, you can rewire and eliminate it, but keep in mind that switch is made to shut the fuel off if you get in a car accident.
The 1993 Probe GT was not turbocharged. The previous generation had a 2.0 turbo. This one is not.
