today, i was with my gf and she NEVER flors her SSEi. well, she was in a speedy mood and wanted to show off since i always am the showoff in my car. she floors it from a stop and the car takes off but has a very steady miss. kinda like it was running on maybe 5 cylinders or something and as it cycled to the bad cylinder, there was a loss of power. it was really bad and i asked her how long its been doing that and she said that its been doing it since she has owned the car. i'm guessing fowled plugs? her dad is supposed to be changing them for her since i have minimal time to work on her car. if its not the plugs, where would I look next?

Id start with new plugs and wires and then move on if that doesnt solve the problem. Also check the battery cables and under the boots for corrosion.

What year is her car. Does she have boost? Check the plugs and post pictures if you can. Check wires. A common problem is the plug wires for cylinders 4 and 6 can contact the O2 sensor wire. Also check the air filter.

its a 1995 bonneville ssei. 61,000 miles, everything under the hood with the exception of the air filter and battery is original
