I believe I have been having a problem with my Mass Air Flow sensor fouling
my plugs, is this something anyone here has seen before. The engine misses
a little, lacks power under 2K RPM and the transmission will slip once in a
while when at a stop light/sign.
I have taken my 2005 Silverado 2500HD into the chevy dealer three times,
first time they said it was a bad sensor on the transmission, second time it
was the computer software, the third time they said they could not see
anything was wrong and no computer errors. If I take it out on the highway
and floor it will run decent for a couple hundred miles or if I run some
injector cleaner though it will run better for a couple hundred miles. The
gas mileage is noticeable better when running smoother, no surprise here. I
have sprayed the MAS with electronic cleaner as it was dirty, no I am not
using a K&N filter. I replaced the plug wires and paper filter. I can not
see the plugs being bad already with less than 16K miles.
I am thinking just replacing the MAF sensor to see what happens. Is there
any real benefits going with the Granatelli or Jet MAF over the stock
Thanks for your time.
