Will miss at the low rpm but if I am in 1st gear and get the R's up if feels like the other plugs start to fire up! If I shut it down for say a hr. or so fire it up and runs like a clock? There was a post I think on this forum where a fella had simular problem and a member replied to it ! but do you think I can find that post?? I am taking car into the shop for new swaybars and shocks on Wed. and I wanted to to talk to tech about this prob and the members idea! Would like to find a solution to this as the car runs great otherwise! So if ya all got any ID whats going on hear I am all ears!
