car has been acting funny lately just wondering if someone could maybe help me out. When i first start my car it runs fine then after about 3-5 mins it seems like it loads up and runs rough(unless floored) and you can smell gas, then after about 5mins of that it runs fine as if nothing happened. would this be the O2's? thanks

my brother's 89 was doin that till 2day when we changed the o2 sensors it ran just about perfect

not to hijack, but sounds like its time for me to get to my 02s

ran codes?

jjw88mustang

nah was hoping i wouldnt have to

instead of guessing and replacing parts possibly throwing money away i'd verify your issue is the o2's. it takes all of 10 minutes to run koeo/koer tests

not to sound to dumb but i havent ever had to mess with runnin codes so dont really know what to do or anything

or you can take it to a shop and have them run it. but its really easy to i recommend trying it yourself.

OR go to autozone and have it done for free. I bought a EEC IV code reader, cost me 40 bucks. My car was originally speed density and they don't have a check engine light so I had to get the reader.
