Can someone take a look and help me out. I feel my car is running a little rich right now. I have a scan at www.ozarkelectric.com/kevin/kev1.csv
I think i have a small exhaust leak on my passenger side headers. Does this prove my theory and what else does it show that i need to know about.

Thanks for the help.

 

Looks to me like its running fine, blms are together and fairly stable at a steady condition. The only thing I can see is that under heavy decel it pulls alot of fuel but it doesnt hit the limit, no need to tune decel though really. Theres no bias toward either side so there doesnt seem to be much of an issue with the leak if there is one, just look it over and fix it if it is, but its not doing harm at the level its at now.

Only thing you may want to do is give your maf tables a little work here and there to get blms closer but if it was my car i would just leave it alone really its pretty good.

Next time give us some town driving/stop and go stuff and dont start logging until the car has warmed up and run for 200 seconds or so, and instead of killing the thing as soon as you stop let it idle a bit so we can see whats going on there too.

What makes you feel the car is running rich?

 

My car has been a garage queen for a few years. Only a thousand miles or so a year. I am starting to drive it more so my wife can have the rainier to drive. So anyways after i installed headers and ram air hood with box i was getting around 25-26 mpg. Now i am down to 21. My drive is bascilly all highway right now.

Thanks for looking at the file for me. I read some stuff at http://members.aol.com/InjuneerZZ/Sc....htm#step%2017
that had been posted and could see anything that looked funny to me. But i have just started to look at this stuff.

Thanks,

 

Have you replaced the o2 sensors since the header install, were the headers coated and new when you installed them? Make sure you have a good clean fuel and air filter just for good measure.

 

I don't know if i did new o2's yet. It has been a long time. Yes the Mac's where new and it has the ceramic coating on them. The coating still looks good on the headers, just not the y-pipe. I figured if the o2's are reading normal than they are propably ok. I hear a little ticking from the passenger side headers so i am going to see what the new gaskets do for me.
