my car is really starting to get on my nerves. first a few months ago it started to chug all the time below 2,000 rpm if i tried to hold it at a steady speed and also it would idle rough like need a tune up really bad. also every once in awile i would start it up and it run bad and the ses light would come on then i would turn the car off. then back on and the ses would still be on after a couple on offs it would quit and do it again a couple of months later but i would never check to see what code it was. all the time it was doing this it was running richer and richer by the day so i thought that my injectors were leaking or getting stuck cuz of how rich it was so i bought new 24# ford racing injectors and it made it run alot better and then it went back to really rich again. and started going up and down idleing so i changed then tps and set it to .50 and that didnt fix it. then about a week ago the ses light would come on and stay on and it would start running really bad with the light on so i checked it and it said code 33. i gigled the connector going to the maf and reseted the comp and it quit and then came back a couple of days later so then i bought an iac valve, maf, and a new o2 sensor and it ran like a champ for a day and now it is throwing code 33 again and running bad i dont know what it can be.
