I bought this car as salvage at auction. It has the 2.2 ecotec engine with 4 speed automatic transmission. It was in a frontal collision. Apart from the radiator/condenser the engine seemed untouched by the impact. I had the front unibody components straighened and a new rad support welded on- the frame shop did an excellent job.
The car starts perfectly and idles smooth but acceleration is very poor. I get a PO0300 multiple cylinder misfire when i drive it but if i clear the codes and
just idle, i get none. It behaves as if it's running too lean.
I've checked for air cleaner restrictions
spark plugs ( all 4 fouled with dry black deposits)
swapped the ignition module
Swapped ECM
replaced fuel filter
checked for leaks at intake manifold and throttle body
i have fuel pressure-just don't know how much
