Duralast TPI MAF sensor, was installed on my 1989 T/A for about 60 miles, but didn't play well with the computer, kept throwing code for high voltage. Seem to be a common problem with the circuit board sensors. If you can program the factory chip to raise the voltage cutoff for the sensor, it's not a problem but I don't have a programmer. Paid $175, sell for $100 shipped. PM me if interested.
