140 across the board for an NA is bad news. That puts you below the minimum. Beyond that issue, you mention conzult. Have you done a power balance test to determine if it’s spark or injector related. How’d the plugs look when you did the compression test? You should also clean every engine harness connector and then apply dielectric grease. Make sure ground points aren’t crusted up.
Lastly, you say you know it’s a MAF issue. What information do you have to support this claim? Did you follow the test procedure for the MAF in the FSM? If you are sure it’s the MAF then buy a new one and try it out.
