just bought a code scanner...

ok i went through the manual and it says that the timing has to be set before u should perform the koer test, does that mean stock timing? mine was at 14* but was recently kinda screwed up, not sure what it's at now but it doesnt ping on 91, would that make much of a difference in the test? thanks i advance

Timing does not need to be set to run any of the scans on Mustangs. The scan tool has no way of knowing what the base timing is.

ok thanks for the clarification, the book said something about needing to set the correct timing before running the tests

I think the only reason they suggest that is that the computer will rev the engine a little while performing the test. If the timing was really off that could cause some problems.
my 2cents

well i havent ran the koer test yet, i wanna fix the tps first then have it show no codes on the koeo test, then do the koer, today is my work on the 5.0 day (no work/school)

I bought a cheap $30 code reader and I love it. A lot quicker and easier than trying to count the codes by yourself. But, yeah timing makes no difference.

also, i think the reader can put the stang in no SPOUT mode for a couple mins to evaluate the timing (ive never done this step, so i could be wrong). just my faint recollection.
