Jose,
WHose car is this?

Where were the MILS's bought? Have you tried new MILS's?
You need to get that car dyno tuned. WHat injectors and fuel pump. Is he running the vortech chip?

whats up bud?
By typing in caps you are yelling> im sure thats not what you want [Confused]
The check engine light could be coming on for a few things. My guess would either be a leak on the bypass valve> loose hose or something> or your O2 sensors have gone bad. What kind of fuel have you been running? How many miles are on these current spark plugs that are in the car?
I would strongly recommend changing them to NGK Tr6's. You need to find someone that will scan the codes for you>> I know a mechanic that will scan them for some $> but im sure you can find someone on this board that will have a scanner that can help you out. The hard start problem that you are having> is that only when the car is warmed up> or> also when its cold? That could be the same problem that you might be having with the spark plugs if you have that problem all the time> but if only when its warm> then its going to be the programming> Byron (the local tuner) can adjust the way your car will start when its warm and cold. Since the car was at APEX> was it dyno tuned? The misfire could also be the spark plugs> or the tune> not enough spark in the higher rpm's.
This should get you started on the right track> hope this helps.
