July 1, 200520 yr well, after moving up to lynnwood and doing the commute from there to seatac everyday i can positively say its still pings pretty well!! is it time to bring it in to smart-service and have them take a look? hate paying the shop charge, especially since i have no idea how long it might take them to find the problem, if they do find it at all... have to sell this before i can even begin to look at xt-6's and i refuse to sell this to someone before i get the pinging fixed...the squeaky brakes on the other hand is THEIR problem please help if ya can... thanx!
July 1, 200520 yr What Ross said, and... ... Tell me what parts you want to try and swap out and I will bring them out. I really need to "make the rounds" this weekend, and Lynnwood is just next door to my stop at edrach's.
July 1, 200520 yr Author havent tried the maf yet other then putting on another one....i would guess the next part would be an injector...
July 1, 200520 yr Alan, try running with the MAF unplugged...that will give us some information to go on. After that, take northwet up on what might be needed. havent tried the maf yet other then putting on another one....i would guess the next part would be an injector...
July 2, 200520 yr By the way, two new Subarus showed up at Lynnwood today. A 87 sedan and a 90 wagon. Both looked like they had SPFI throttle bodies.
July 2, 200520 yr Timing is set to 20 degrees advance; just where it should be. set the timing back -Brian
July 3, 200520 yr Author okey doke, update time....disconnected the maf yesterday...car runs better! smoother idle, quicker acceleration, no hesitation or bogging...cant tell on pinging till i go to work tomorrow at seatac and see if it pings at the normal areas of the hiway....but, so far so good...but, why is it running? i will be tracing the wiring as suggested to see if i can find the short i guess but i didnt think it would even run w/o it connected...maybe it defaults to rich?
July 4, 200520 yr As mentioned earlier, when you disconnect the MAF, the computer goes in to a "limp home" mode that allows you to drive. It regulates the amount of fuel based only on the engine speed and tps. This gives it a rough estimate of how much fuel is required, but it will run slightly rich under most conditions in this mode. If the pinging is gone, i would have a very comprehensive check for inlet leaks before moving on to other things.

July 4, 200520 yr Author ed have to work on the 4th but will take you up on your offer hopefully sometime this week... thanx! alan
July 6, 200520 yr Author havent had the time to scope out each wire but have noticed that w/o the maf on the engine will not stay running when first started after a day or night off...if i keep the rpms at around 2-3k for about 30 seconds it will then idle fine but not otherwise...seems to show at least one of the maf wire connections was working anyway
