I have a 97 gst spyder 2.0 dohc 4g63 head with a cyclone manifold.
Originally got the car with bent valves. I replaced the head with an older one with the manifold. I got the car started but i have to give it a shot of starter fluid first.
It Idles but feels like it is running on three cylinders. I also ran an obd on the car and came up with a Manifold differential pressure sensor circuit malfunction error.
I checked to see if there where any vacuum lines loose but nope !
I did notice a little difference from the original manifold( it has an egr valve) the cyclone manifold doesnt so the sensor is just hanging there. would this affect the way the car is running?
How about if the timing is off a tooth or two, would that affect the car dramatically to where t would feel like it was running on 3 cylinders and very rough?
When I push on the accelerator, it dies !
Please somebody help me !
