My schrick is not working correctly. I need some help.
what it should do. start car led turns green, 4000rpm turns red , controller sends signal to vacume cyliniod and valve opens, 3950 coming down valve closeslight turns back to green.
what is happening.
start car.. light turns green. when the t.b. adapts and kicks down the light flashes from green to off. actuating the vacume cylinoid opening and closing in about 1 second intervals. Tach inside care is going up and down slightly at the same intervals.
what could cause this to happen? bad tach signal maybe? any help would be great.
