im curious to know if the egr simulator is actually worth getting and where can i find the meaning and how to fix the trouble codes my car is showing the cel for

If you are deleting the EGR.....yep, it works....it will only cause a code 33 KOER or KOEO/CM to show up but the CEL will not be triggered.....which codes are showing up?....

LIL D

koeo- 91-41-34-85-67
91-41 are o2 codes
67-nuetral drive switch
one is a canister purge code and the othr is an egr switch code

koer 12-21-41-91-34

i replaced the egr swich but havent checked the comp since then i have ne wo2 sensors butim not gonna put them in til i build my new motor

Don't unplug the sensor connector, leave it on....simply disconnect and plug the vacuum line to the EGR valve. The only code that will show (assuming the EVP sensor is OK at its closed valve value)....would be code 33. The CEL will not turn on due to code 33, the only codes that will turn it on (EGR wise) are codes 31 and 35 (open and short in EVP circuit).

^^ that is not true...

im showing codes 33,94,44 all EGR/AIR related

CEL flashes like crazy when the car is warm and running at a set RPM for long periods of time.

i Solus scan the car daily...

33 itself will not trip the CEL... i double checked that one myself on my car. I unplugged the egr vac hose and left it that way for two days... scanned my computer, code 33, no CEL
