hey guys..

Need some help.. Just picked up a 98 accord v6.. I have been driving civics and preludes all my life but the accord is very new to me.. I have a check engine light on and I am getting the following codes..
- 12
- 71
- 72
- 75
- 76

I know what the codes are for but any idea what would be causing them?? The car runs good.. But feels extra slow.. Can't really tell if vtec is coming on or not.. Is vtec on these cars pretty quiet?? Would these codes cause the vtec not to come on??

Thanks

Does it accelerate properly, or does it feel like it's starting off in a gear range other that 1st?

It lookes like possible tune-up issue mixed with the dreaded transmission problems.

It can be the EGR valve stuck open, which can cause the random misfires.

Your gen Accord V6 also had a common problem with EGR clogging:

Why would you buy a car with the check engine light on?

It was not on when I bought it.. Thanks^^.. Anyway.. I cleaned the egr valve today.. seems to be running better.. No engine light yet.. When you accelerate around 80-100 kms the pickup is terrible.. Is this something common with these cars?? I know these cars are not that fast but I have felt a neon pull better at 80.

Thanks

It almost feels like the throttle is not opening up all the way when the pedal is pushed to the floor.

check that the cats are not clogged
