this problem will come and go... it will do it when the engine is cold,hot,morning, or even after driving after 2 hours
what i cant figure out is somtimes it will go away for a couple days then come back. it hessitates(hiccups) starting from stopsigns but usually it will happen during driving at normal speeds. my AIRfuel ratio gage (autometer) will stop bouncing from lean to rich and it will slow down and get stuck eather rich or lean. for a coulple of seconds.... then it will get better for a while.
i cant find any vaccum leaks
new parts on car
fuel filter, fuel pump, aic, amm(2years), bov(1year), vac lines, plugs/wires/cap/rotor,
temp sensor, o2 sensor(6 months), injectors(3years), fpr(3years).
check engine light codes read:
12112 incorrect a/f at idle
12114 incorrect a/f driving
12111 o2 sensor,elcd,air/fuel leaks
any ideas?
