Has anyone successfully found the causes and fixes to these error codes? I have a97 w/ 38K miles and cannot get these to go away. Also, when I hit overdrive I have some shaking any ideas?
It seems like there are a lot of threads going on with these, but no conclusions...txs

1178, Maximum Positive AMFR Correction Fault
1316, is Misfire Excessive Emission fault.
The 1178 is a bugger to find and fix, can be a vacuum leak, the 1316 is leaning towards plugs and or wires.
Has the truck been tuned, what octane gas are you running?
May want to consider a good induction cleaning after the tune up.

Both have been a pain. I have changed the plugs(champion), wires, and have seafoamed the intake and added to 92 octane gas. No obvious vacuum leaks that I can see. Has new gas filter and pump. Wonder if the O2's are bad, not sure how to check them. also, cleaned the MAF with appropriate cleaner.
