Check egr valve hanging of the front of intake manifold.

Check connector to #3 sensor (watertemperature sensor on R side

cylinderhead between auxilary air valve (also potential vacuumleak source)

and port 1 of exhaust manifold

Check connector #2 sensor (air temperature sensor) in airfilter snorkel area.(or can leave disconnected)

Hose from intake manifold to Manifold Air Sensor (i once had one routed

under the hood hinge...car ran fine with hood up, as soon as I slammed

hood, stumble and stall!!)

hope this helps
