After I had mine regrounded, the car ran a lot smoother, throttle response was a lot better too.SE-Rican said:
If it's improperly grounded, the car will run too rich, you'll have terrible city fuel economy, it will be very jerky on and off throttle.SE-Rican said:
dgerryts said:what you are actually measuring with the volt meter is the voltage drop of the ground circuit for th MAF. If the voltage drop is to high, the ecm gets an incorrect reading for the MAF. Grounding it elsewhere clears up this problem.
dgerryts said:a voltage drop test is much easier and alot more sensitive than an ohm meter. The second thing is that the voltage reading should be taken when the engine is running, you can't do this with an ohm meter.
