Yeah, let's see who's doing the reaching w/o any info to back it up

For example: customer with Avalon pulls in with engine performance issue and MIL on, checked code and data stream, needed at least 80% calculated engine load @ WOT, was way below that spec, MAF heated wires and temp probe were gunked up with sludged, cleaned MAF meter and installed WIX filter, cleared code and let customer test drive his car. He couldn't believe the new throttle response and wanted to know what I did...told him I removed his K&N filter that he said was just installed, and they come pre-oiled so if it was over-oiled it was done so at the factory; nothing else could have put that kind of oil build-up in the MAF meter so quickly, other than the non-paper element that was upstream a few inches.

I believed the customer because he was about 70 years old, driving an Avalon, believing the salesman that pushed the K&N filter on him because it'd get him about "10 to 20 percent improvement in fuel economy" ...and I've also seen lots of vehicles with blow-by and PCV problems during the last 26 years, this Avalon showed only signs of fresh, clean sludge build-up on the heated wires, no dirty engine oil anywhere in the air intake.

Don't remember exactly on the Avalon, sure wasn't a beater; fairly late model (I do rembember that it was OBDII) and appeared to be very well taken care of. Main thing about the Avalon was that the MIL was on, couldn't get above about 55% calculated engine load @ WOT on the datastream, and had fresh oil buildup on the sensor, not the typical gray/tan dry ash coating that I come across.

It could have had 200,000 miles on it and he had just got a brand new K&N filter and we blame ALL on the filter and nothing else? It could have been used as a pace car for NASCAR or on some dirt track...or maybe it could have been used as a Cab or a rent car. But I guess it doesn't matter since All evidence points to the K&N
