HELP! My 98 Neon SOHC started Idling rough. Showed Code 32. Changed EGR valve and repaired pinched EGR Vac hose. Worked fine for a few days and started Idling rough again and stalling at idle sometimes, now shows code 52. O2 sensor and wiring look fine. Gets good spark and good fuel pressure. Gonna try cleaning the throttle body and IAC. Any other sugestions will be greatly appriciated.

 

when was the last tune-up? if air filter is clogged/plugs worn might not get a good burn. pcv valve? give those a look. if look ok change the o2 sensor. good luck.

 

Fuel pump system might be shot as well.
