wells MAF question
I bought a new Wells MAF to replace my Bosch(I stuck my finger through one of the wires, I know ,I know
).But after installing the Wells my car has a stumble off idle that it didn't have before. The Wells unit is different inside in that it has a circuit board and a piece of foil inside instead of the wires and heat sinks that are in the Bosch.Is the Wells compatible with my set-up. thanks Stewart

If it's the SU 145 then it's compatible. The wells is designed to use the more reliable circuit-board style electronics like the LT1 MAF uses, but with an output that's compatible with our computers. I'm running one on my GTA and it works beautifully.
