[DaRussian]

Hi i have a 94 integra ls and whenever i drive the rmps jerk up and down, what could be the problem

[Vuongy_Dong]

does the car jerk or just the rpm? could be the speed sensor.

I'd check those sensors in the following order (which assumes that you'll be swapping them for ones that you know will work): MAP, IACV, TPS. The TPS is part of the throttle body, so you'll have to swap the whole thing out to test it, which is why I'd do it last. You may want to first try to ziptie the MAP sensor plug to the sensor (add a drop of superglue on the corners opposite the plug, but just a drop, so the ziptie does come right back off).

thanks guys i got it, my distributor was loose lol. sounds so stupid but i opened my hood today and first thing i checked to see if the distributor cap was clean inside, but it was loose and the whole distributor was wobbling lol, the car been standing at the shop for months so somebody must have loosened it
