Hey eveyone.
The other day I changed the spark plugs in my GTP. I use the AC delco from GM. the gap was already set .60. old ones looked ok but i wanted to change them. I also changed the S/C oil. after allof this i took it out for a drive after it warmed up ane it ran perfect. then we went to the city ( 2 hr drive) when we got close i decided to pass a ricer. well dam when i started to get it wot the car started to chug or miss, like hitting water puddles as one guy told me.did i do. I checked the wires all is good I'm lost on this
plzz help thanks![]()
