98 Disco 1 LSE. 138k. CEL on with P1176 code-Maximum Positive FMFR Correction Fault .

No problems, truck runs great except an occasional (one morning every 2 weeks) high idle.

I've reset the code, it takes about a week to come back.

What specific steps to troubleshoot? Thanks.

I agree he is most likely right. I knew it was probably the MAF when I posted. Just thought there might be a few cheaper alternatives to try first.

Do you know anyone else with a DI? See if they'll let you try theirs for awhile to confirm. If not the best price is Will Tillery aka www.roverguy.com and is highly recommended. Call him though. He's a busy guy but has a cell phone glued to his head.

Good Luck,

Mike

I used some several moths ago. Everything was running smooth, but I used it as a preventative maintenance and it seemed to clean the MAF up a bit. That reminds me, I should probable hit mine up again, I'm starting to run a little rough.
