Answers :

It's your "slow ideal valve" It's located on the intake manifold, near the driverside. There are 2 screws on top, remove the screws, Next get a flat head screw driver, now your gonna see a white plastic like saucer shape piece in there.. Now your going to turn the saucer shaped piece clock-wise and your screwing it back down, out the lid/cap back on, tighten the 2 lil screws, and start the car, the up nd low idle is gone..!!!!
I have a 90 honda accord ex, manual transmission with 160xxx miles.. when accelerating in any gears, it'll pause then accelerate.. doese it have something to do with the ignition systems or is my transmission no good? please help. thanks!
