I posted while ago about my 1990 3.1 z24 manual sometimes when she is warmed up and shut off for few mins and started again that it runs really bad smell the gas like a real rich smell and the rpms shoot up and down and the car is boggy jerks back and forth if you try to drive it. then if you drive it for few mins it gets alright its driving me crazy when it does it i have to wait like 5 mins for for to calm down a little so i can drive it to get it to go normal i replaced the O2, EGR, CIS, TPS, and fuel filter and still same problem any ideas
