Hello all,
I am new to this group and was not quite sure which forum to post this under, but here goes and we can move this to the appropriate area if necessary.
I have a completely stock 89 GT. I have some sort of a problem either in the fuel delivery system or the ignition system. After the car has been running f0r a while, when I get to about 1800 rpm, there is a hesitation in power and then once it gets past that speed, it seems to resume normal function. As the run time continues, the problem keeps getting worse until it is almost undriveable. Somebody watching me would think I did not know how to drive a manual transmission.
A friend of mine was following me the other day and observed black exhaust indicating it is running rich, but I already knew that because I use almost a 1/4 tank of gas going to Walmart, which is outrageous.
I have also noticed the temp gage is completely bottomed out. I do not know if it is related, but I know the gage and the sensor must be working because I have noticed it in the normal operating range on occasion.
My mechanic was unable to offer a solution, but he was able to observe the problem. We discussed things like catalytics getting clogged, fuel system needing a cleaning. He did change out the thermostat, but the temp gage problem remains.
Anybody have suggestions on where to go with this?
Thanks,
Andy
