Getting 0300 code. help OK, well, You may call me stupid after reading this , but we all make mistakes. About a week ago I thought I got bad gas from chevron so I went to the store and bought 2 octane boosters. I put both in my car and now my torque convertor wont lock up and my car wont idle nor run and also the rpms are jumping up and down while driving..Slower then A civic at this point. Now after putting a complete new tank of gas.. MY car is still running terrible and still throwing this code. any suggestions?
Thanks Landon

are you setting an SES Light? If so, what are the codes?
And don't use octane booster again ... kills spark plugs if used enough, and overall waste of money
try resetting the PCM temporary memory... pull the PCM Bat and PCM IGN fuses with key in run position... toggle key run stop run stop a few times (not sure if this is necessary but I do it), replace fuses.. it'll idle poor since it has to relearn idle and fuel trims...
