Yeah most of my cars are OBD I or no computer ( 84 Laser XE, 86 EXP, 94 Sidekick, 89 Mark VII, 78 Mark V, 70 Mustang, 72 Stingray, 81 Honda Civic, 1936 Cord 810, then 98 Mercury Grand Marquis, 2020 Volvo S60 T8 Polestar, and 2021 Lexus LC500 convert.) and diagnosing OBD1 or finding someone who remembers or knows is a PAIN! so THANK YOU for your help. That being said I found MAF from SKP, WalkerProducts, Cardone, Delphi, Beck/Arnley and WVE. The tag on my sensor is 13800-58B00 (next line) E5T53071 4509. Ive heard of Cardone ( I sold auto parts for years, Napa, Advance, Pep Boys, AZ) which Ive had issues with and BECK and Delphi.. Any suggestions??
ecu reports only dead maf not weak .
explained
the ECU uses the MAF for all fuel mix calcultation
it also watches (DTC monitors live) f
for stuck high and dead
and stuck low and dead.
both will set the 2 matching DTC codes.
example, 1:
if the maf should read say 3v at 70 hp engine power but is 2v you do not get that power level (it goes lean) but the ECU simply likes that wrong 2vdc level it is happy as a clam. (but not us ever)
'see?
