Im getting horrible hesitation in upper rpms. (not sure if this is 'missing' or not)

A few days ago, I had some debre in the MAF that I blew out with a can of compressed air. (cleared the MAF code) But I did drive home that day (about 15-20 blocks) with the MAF unplugged as it wouldnt run with the bad MAF.

After I fixed the MAF problem I got codes 0210 (front bank lean) and 0304 Knock sensor and now this hesitation/(missing?) after 4000 rpms. Cleared codes again, havent got back the 0210 but the 0304 came back again.


Knock sensor resistance is about 5 M ohms. Vacuum seems ok, about 22hg, what would a reading be if there is a vacuum leak? Fuel psi is normal.

Car idles normal, and drives normal under low to medium throttle and in the lower rpms.

Any thing else I should check before replacing the knock sensor?

Thanks.

Check your coils.
One or more of them might be failing.
I think it is in the "How-To's".
If you need to replace them, get the Mitsibushi ones and not the Hanshin replacements.
