So my check engine light has been on for a little while, I haven't had the power I used to have, and when I floored it (once), the light started blinking at me. That scared me so I didn't do it again. The other day I took it to a trusted mechanic who said I had three codes in the computer--bad cam shaft sensor, and two cylinder misfires. So he replaced the cam shaft sensor for me, and recommended (given the 90k miles on the car) that I do spark plugs, fuel filter, and air filter. I haven't gotten around to the fuel filter yet, but I just replaced the air filter and spark plugs (with OEM ones). So I reset the check-engine light (by pulling the battery), start her up, and drive for a bit. Everything seems fine. She's running smooth, no lights on the dash, etc. So I goose it a bit; and when I hit a little over 5k rpm, right as I think "wow this thing still doesn't have the kick that it should", that damn check engine light starts blinking at me again. It blinks for about 30 seconds and then stays on solid.
Right now I don't have the time or the money to bring it back to my mechanic yet again. I was hoping some of you could provide me some educated guesses on what might be causing this. Given the lack of power, I'm personally thinking I'm still having cylinder misfire problems. What else could cause that, apparently only at high rpms?
Thanks for any ideas at all.
