So this afternoon i took the time to pull some stored codes and was wondering if you guys knew what route to take next or is in need of being replaced, i pulled
173
327
328
334
337
634
And another question is are all these EGR codes going to be in direct relation to the same part that is bad?
This is on the 92 302.
The 173 code is not a KOEO code but in KOER and CM it means system is rich.
327 is the opposite of code 334.
328 is the opposite of code 337.
You can not have opposite codes.
634 says the MLP sensor is out of range.
Are you sure you have three digit codes?
These do not sound right at all.
Sounds like then you have a lot stored codes in CM then.
You need to clear the codes by grounding the STI wire, turn on the key and when the CEL (MIL) starts to flash remove the ground.
The the codes will be cleared.
Then turn the key off.
