Air FIlter

you can set the time scan. It has instantanous and per tank, as well as previous trip. The handy thing is the % load on the engine. That allows you to keep at a set load and see the changes. Actually if you want to save gas you want instantanous, as ive already went from 19 to 22 before the air cleaner with just the scan gauge and bt keeping the % load under 30%. The scan gauge is dead on the money. All the scan gauge is doing is what the trip computer would do, just reading the info off the ecu. nipper -

same brand i always use purolater. nipper -
I have a scan gauge on my 97 OBW. Car is getting inspected in a few days, so i did what i could do. i bought a puerolator air filter. i looked at the old one, i kicked myself for buying a ne one, as the old one looked ok. ive only put 3000 miles on the car in the last year because of my back. Well i put the new airfilter on the car and i gained 2mpg. Shocked me as i didnt think the old one was that bad. normally i say when figuring gas milage do it on three tanks of gas, except when your reading directly off the ecu. i find it easier to compare things in real time since there is a percent of load feature, which can keep you consistant and see how changes affect mileage. nipper

Do a search here for the bulbs. This is a standard problem. if you can replace miniture christmass lights you can do this. Fuel sender has sulfur on it. Go to the autoparts store and Chevron has a additive that cleans the senders. I did it on mine and my gauge is 90 90% accurate instead of completly offf. inspect all wheel bearing, and the front cv joints. nipper

there is nothing wrong with the switch. Get a manual or do a search on this. There is a resistor block in the air box under the glove box. High speed is a direct feed to the blower motor. Lower speeds go through resisters. You need this block. Buy a new one, as used ones that work are few and far between. nipper

hrmmmm a few questions when was the last time the timing belt was replaced, and was the thermostat replaced at that time. When you turn the ac on do both fans come on is one radiator hose a differnt temp then the other When if ever was the last tiem the cooling system was serviced. AGAIN ill ask how fast does this happen. nipper

even more technical the vscous coupling is made of altenating plates with calibrated holes in them. This all sits in a viscous fluid. The spinning plates at differnt speeds shear the fluid, creating friction, which causes heat. The fluid as it gets hotter becomes thick and transmits power. The size of the holes in the discs determines when this happens. nipper

soobies are pretty good that way, upstream doesnt usually make a failure downstream without throwing multiple codes. The solo failures which are reliable are o2 sensor (which can be confused with a bad cat... cat is usually ok) speed sensor(s) knock sensor position sensor (cam or crank) evap purge valve (i think thats all) Tranny codes are clear cut. The others usually require a good think nipper PS of course my car goes in for inspection this week, so yesterday it threw an o2 code. i cleared it with the scangauge, and hoping it stays away.
