for the last couple of weeks, i have had a prob from my car. between 800 rpms and 3000 rpms it sounds like it is clogged and gasping for gas and air, and feels like a miss and is very hesitant. i have just installed some Beru spark plugs, so it is not them. i checked the entire car over today and nothing. no check engine light, just smells like it is running rich. any body else expirenced this or any possible ideas?? thanks

 

did it hesitate before you changed the plugs? if no, the plugs are the problems. are u running nitrous? why didnt u just use the OEM NGK plugs?

 

My friend, my car does the exact same thing. How many miles does your cl have.

 

my car now has 180,000 miles one it.i started about 1 month after i upgraded the entire ignition system. i tried beru because nology makes them and are suppose to be one of the top for racing so i thought i would try it. my check engine light just came on and it says cylinder 2 & 4 missfire. ?????????????????????????
