i own 2 98 Pontiac sunfires. A 2.2 5speed and a gt 2.4 5speed. The gt is being a pain..for months now i have had nothing but issues. 1st it would not idle, codes system to lean bank 1, p0138, and p0507, i replace the following, iacv, tps, both o2 sensors, air temp sensor, map sensor, cam sensor, fuel pump, fuel pressure reg, plugs, boots, coils, ign module, checked all vacuum lines,throttle body gasket, problem has gotten worse, not when u give it gas or a load it misses and breaks up, i have no idea, all the same codes come up.....anybody at all have any ideas? This is aggravating me.When the car runs its awesome.....unfortunatley it doesnt run very often...any ideas at all
