I actually have a 1986 Corvette. It has an OBD-I code of 034.

Specifically the code is "Mass Air Flow (MAF) Sensor voltage is too low." I'm reading that it may be a vacuum problem. Does anyone know where to start with this repair?

The car has 42K miles and the following have been replaced in the last 2 months: MAF x2, plugs, wires, distributor, coil, battery, throttle position sensor, PVC valve and the engine computer. I also have a new fuel filter to put in.

I've got a check engine light and the erratic running engine symptoms. I'd appreciate any help.

Snap-on Modis scanner will do a bunch of good here... live data is critical... Be sure the maf tube is in good shape and tight! Possible wire/connector issue... can't help much over the net!!

Thanks. Wiring is where I'm heading first, then vacuum. I appreciate the response.
