The owners manual won't even tell you where your spark plugs are.......you need a decent repair manual to follow.....go to the fuel section of it and it will tell you the correct proceedure for testing them and exactly what to look for (ie what are "good" and "no good" conditions for each component). You will need your new DMM to do any of this type of testing tho.

 

Back up to 21.8 mpg........

 

Hey Bumpin Yota...

About that 21.8...I take it your mpg went up a lot with an O2 sensor replacement. What were you getting before and did you change anything else for that improvement or do you think it was all about the sensor?

Thanks.

 

Well that 21.8 was highway driving @ 70mph, before I was getting about 19 at that speed, so it was roughly a 3mpg increase. Im hoping for more of an increase as the ECU fully adjusts.

I'm on course to get roughly 17-18mpg around town revving the engine at every light. Still not as powerful as I'd like, but it's getting much better milage thankfully.

Don't mean to bring this post back from the dead but...I am having serious mileage problems.

I am getting ~10.8-11.2 MPG city...thats with my lead foot and ECT part of the time. I am thinking it is either a bad 02 sensor, bad AFM (Air Flow Meter, thanks to robinhood) or a clogged cat.

There is a pretty bad smell that comes after I rev the engine a little. The smell isn't constant though, usually only after running the engine for a little bit. It is acting like the 02 sensor is about to go bad...I am thinking I should take it to the shop and have them check everything out. What do you all think? Any of you that know me and my lack of skills should know that I am probably not capable of doing any of the diagnosing myself...

Comments/Questions?

Thanks,
