couple of stupid questions
also... where can i get my car scanned to see if i have detonation or timing issues? the car runs fine, no misses, but at WOT it sounds like have little BB's in the motor and a knocking sound.... i've tried different gas stations (93 octane everytime) also i cleaned my maf... it's worse in hot weather.... can somebody help me out here
Should be fine without a cap but a cap probably looks better

Any auto parts store should be able to scan it for you.
