have been running rich (14 city). So decided its time for the tune up. K&N, did a seafoam. car is running smooth. New NGK spark plugs, AMSoil, large oil filter, tire pressure checked. After reading through all the earlier posts, decided on the following too:

ECT sensor (blue)
Pre cat O2 sensor
Fuel Filter.

can any1 suggest any other tune ups and a better placeto buy the above listed. I have been looking around but bumped into some real pricey ones. BTW i need the pre cat sensor.

Thanks

 

you must fit a spark plug arrestor which takes the secondary o2 sensor out of range

 

basically what it does is create a space from the front sensor( if it has 2 ) so they cant calibrate

 

ECSTuning.com has O2 sensors, pre-cat sensor with shippingcomes about $160.

hey thanks for the response......how about the ones on purems and ebay???

any other tune up suggestions?? can i get a DIY on hoe to clean the MAF....i was going through the posts and found that the K&N filters generally clog up the MAF.....So....i thought its not a bad idea to clean the MAF too......

can i get DIY for this??? i coudnt find one......

 

they only clog up depending how the oil in the filter wants to be, if it behaves it won't leave residue, if your your out of luck. You might as well buy two o2 sensors from vast, its only 60 bucks more andyou have a spare, that's what I did/my thinking.

 

wer did u buy the sensors from???

 

vast, www.vastperformance.com

 

Stay away from ebay unless they are bosch. If you can splice wires you can use universal oxygen sensors

 

techbod what are you talking about??

yeah ive been getting around 13-14mpg with my 98 2.8 quattro w/ 108,000miles. im doing the tune up right now as well.

a DIY on the MAF or O2 sensor cleaningwould be great.
