1994 TR4 Check Engine Light

[plauver]

This is my first post, so just let me say I've been looking around here and really appreciate the advice and knowledge of your experience.

My problem-I did a diagnostic jump and got 25 and 26. Which translates to Air/Fuel ratio Rich (25) Air/Fuel ratio Lean (26).

I a little history. This is my first TR4, just bought it and the owner before has taken off the Cat. Converter. It has 138,000 and seems to be in extremely good condition. It has a V6 3.0 EFI in it.

My question is, do you think that the Cat. Converter has something to do with this check engine light? Could you shoot me some ideas where to start on remedies for the Air/Fuel Ratio.

The plugs have been changed just need to put on a new distributor cap.

Thanks guys!

I don't have a cat under mine, so my answer on that would be NO.

Could it be a MAF/MAP Sensor that has failed? Causing incorrect readings, throwing the air/fuel ratio off?
