pulled some codes today

[Macs Stang]

ok, i picked up a digital code reader today and i pulled the codes.

for the KOER i got 33 (egr valve not opening properly), 41 (HEGO (HO2S) sensor voltage low/system lean)

i am pretty much sure that the 41 code was tripped because of my passenger side o2 sensor.

what do you think about the 33 code? does that mean that i need a new egr valve?

i cleared the memory codes from a long time ago, and when and if the ce light comes on i will pull the codes again to see what i have.

thanks for your help,

Tim

i think it's the EGR valve position sensor... it's pretty common on these cars it seems.

check to make sure that the green vac. line did not melt on the egr tube coming up from the header.

i replaced that vacuum line last year, i am pretty sure that it is the egr valve that is acting up.
