I just took the 3130C out to the car again and noticed the STFT is within tolerance, which is well under 10. However the LTFT is at 36 and goes up to around 43 at times when I push the throttle. This is from what I have found out to be a for-sure problem. Any hints on what to check now? Maybe it is as simple as a vacuum leak and I just need to replace all of the lines. Couldn't hurt I guess. What say all?

Cheers,

Howster

Have you checked for exhaust leaks at the manifold or where it meets the mid-pipe?

Hi. No I haven't yet but I will check that this weekend. Thanks for the table as well. Would you look at vacuum leaks first or look at the exhaust manifold?

Cheers,
