Troubleshooting some boost fluctuation

by on Oct.17, 2009, under Logs, Repairs

I bought a MBC and a used N75 valve to try and correct my fluctuating boost. I don’t install the MBC but I do install the N75. The N75 doesn’t seem to help and after the install I have a “Signal too low” code for my MAF. Swapping the MAF with another doesn’t resolve the issue, it appears one of the wires in the harness may be broken. Dammit.
