TPS

Did you cover the TSP with silicone or somthing to water proof. Don't know how water proof it was origanly. Would be a drag to get water spashing up there from a big puddle and getting stuck.

Also I heard alot of talk about K&N air filters screwing up the Mass air sensor with oil. The link,

mentions it is a heated fillement and sensor. Could this be cleaned with some sort of degreaser with out hurting it? Seems like a heater fillement and a thermo couple could take it. Any one know?

Hey, I was reading that site quickly... and I read that a symptom is poor fuel economy and an erratic idle... both of which i have. I have an 88 4Runner V6 and i get about 300kms to the tank (which i feel is rather poor... correct me if i'm wrong). But my idle is weird too... If I sit for an extended period of time (say in rush hour traffic) the idle will drop to ~400-500RPM. Which is rather low considering its supposed to be at 800RPM. So when i go off roading what happens is it stays low like that constantly so i'll adjust to 800 and it will be fine until it cools and i restart... at which point it will stay at

1100 or so... which is mighty high... Then again it will drop to around 500 or so rpms. its so fricken weird... and when its so low... it runs somewhat poorly. I know this sounds confusing... but if anyone wants to help, i'd like this situation fixed :)

Thanks,

Mike.

Read my page (as previously posted) and test out the TPS and you can find out if its good or bad. Its mainly the idle position sensing (IDL) that casues the erratic idle. Its what tells the ECU to idle the engine, vs. run it at a very slow speed. If the IDL signal is missing, you'll not get the nice steady idle. Could also be a sticking throttle linkage or plate that is letting the throttle close differently each time, producing different "idle" speeds at different times.

I didn't seal with silicon and it wasn't originally sealed except with the rubber part. I don't think there would be a problem with splashing in and getting it wet.

Q

huh ?? if oil is getting in MAS then too much oil is on the filter !!

Their is a alot of mis-information about K&N filters.

Are K&N Filters effective? I have taken the position that they are not for two reasons. 1) I sell Amsoil Air Filters. 2) I have done a lot of research. I have stated in the past that K&N filters are marketed totally on the premise of air flow. They typically don't address filtration efficiency as part of the equation. Air filtration is a balance between 1)Air Flow

2)Filtration efficiency (particulate removal) and 3)Carrying Capacity over time (effective filter life). I have seen numerous studies that employ oil analysis which demonstrate much higher ware rates and dirt ingestion associated with the use of K&N air filters. I read recently where Cummins Inc. have come out against the use of K&N filters in their engines.

Amsoil 2-Stage Air Filter Your engine"breathes" air to mix with fuel for combustion - about

9,000 gallons of air for every gallon of gas. And there is a lot more dust and grit in the air than is generally realized - over 400 tons of suspended dirt in a cubic mile of air over a typical city, and more in rural areas with frequent travel over unpaved roads. Remember, DIRT is the greatest enemy of an engine and 90% is ingested through the air intake system. 60-80% of engine wear is attributed to DIRT.

Thats all nice but not what i wanted to know. thks anyway

and yes if 2 much oil on filter then it could get on mas just wanted 2 know if mas could be cleaned?

of course.

they dont recommend scamsoil ones either.

when in doubt, just get the OEM filter.

Whoa, what a novel idea!!! :>))
