I have a 97 with a 2.5L. It is running very poorly and has a flashing check engine light with the codes P302, P202 and P300. I've replaced the cap, rotor, wires, plugs and the fuel injectors. I also replaced the exhaust manifold last week. Any idea on what could be causing these issues. Fuel economy is really down as well and it smells rich at the tail pipe.
Thank you
