I didn't have any spark so i switch out the whole internal distributor from a 1.5 dx obd1 to my obd1 1.6 si distributor. if the car is just in neutral i could rev to 7200 rpm but if i drive it and step on it, it won't go more than 5200 rpm. it seem like it want to go over it but then it get kick back under 5200 rpm like a rev limiter. i need major help cause that is where all the power is.
