2001 civic wont go over 30 mph, new NGK plugs and Fuel pump the only codes I had were p0301, p0302 misfire check coil packs good unplug injectors and car runs rough on each cyl
JA: Have you seen the misfire code before? Has the car been stalling?
Customer: no have not seen code before, does not stall idles a little rough, I replace fuel pump
because it was leaking and we smell gas, after about a week of replacing pump started having this problem don't think they are related, took fuel pump out looks great
JA: Are you fixing your Civic yourself? What have you tried so far?
Customer: yes, new pump new plugs ngk,
JA: Anything else you want the mechanic to know before I connect you?
Customer: check cat seems good have a lot of exhaust
