*Threads Merged* - Rich had moved your previous thread into the appropriate section for you. No need to create another thread on the same subject. That is the very definition of Double Posting. Please read through the rules of the forum and if you have any questions, do not hesitate to PM a member of the staff.

Please have patience to allow others to reply. If you need help faster than that, you could always take the more costly approach and pay a mechanic. Otherwise, please wait for the free advice you are asking for.

How was the O2 sensor output when you had it on a scanner? How about the MAP sensor?

 

From the sounds of your replies to other threads, you are still battling this issue with your '93 tbi. If that is the case, what have you done since the end of September in attempts to fix the problem?
