hi guys which means the code 538 where I have to look to fix the problem is a thunderbird sc 1994 if any one have good advise it will really help thanks
 
i believe you get one flash from the check engine light...then you go full throttle and release.
 
Thanks for the info. This is the only code that shows up. I had a miss in the idle that kept getting worse till it would not even start so I went through everything and it was like all the plugs were fouled out so I changed the plugs and both o2 sensors runs great now. 538 is the only code in koer also have 565 in koeo purge canister sensor failure. Can this code cause the 02 sensors to go bad or the plugs to foul?
