I need to know what is next on my list, I have replaced my plugs and wires, and had my cat and u-bend cut out, I still haven't gotten an o2 sensor emulator, as it is the weekend, my car still bogs, stalls, idles rough, and struggles at high rpms, and my fuel efficiency has gone from 450+ kms in town to under 300, it sounds like something else could be clogged other than the cat that is now gone and I can smell gas, what could cause it to run rich? And would it be the same thing that is causing the misfires and poor idle and poor acceleration? My next plan is to replace my coil packs... Any thoughts and inputs ASAP are very appreciated as I drive my car for a living and haven't been able to work in almost a week... I need my money maker to run tip top!!!
