Have 93 fox with new spark plugs,new coil, cleaned maf,new air filter.
The car cruising run good but at wot the car bog and hesitate exactly at 3k rpm, sometimes even don’t respond to throttle and die but turn it on and runs.
Today it give code 11,63,33.
So I've got a code 33 (along with a 41 and 91 which are both for the o2 sensors which I'm fixing in a few days). Something about the EGR valve position. What can I do to fix this?
