[quote:3e0857c134="redragon"]toyota corolla 1989 400, 000 k's 1.6 l sedan. when i drive the car for a little while it will heat up and then the problem occurs when i am accelerating with the pedal right down at first it will buck and jerk a little and loose a lot of power and then later on it does it worse and worse and it feels almost like a misfire. i have platinum spark plugs in could it be those ive heard that they are not very good for imports i have cleaned the egr valve the vacuum, i cleaned the fuel pump i have checked the whole ignition system.[/quote:3e0857c134]

I had a customer back in 2000 w/a coro with them platinums and made it act crazy told him get the OEM,took a 10mins job and the love of God.
