whats up bud?
By typing in caps you are yelling> im sure thats not what you want ![[Confused]](confused.gif)
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.
