no not sure what scotch lock is, i soldered the wiresA properly installed (and functioning) stick should eliminate the p0299, p0401 and p0404 codes. These codes are usually due to opening up the exhaust or adding an aftermarket intake.
You didn't use scotch locks did you?
The stick won't stop the codes from a bad valve. If no exhaust or intake mods, you could easily check by disabling the stick (blue wire? - I would need to check, but basically take the EGR input out and it will pass the MAF signal unchanged) and pull the plate and see what happens.Minisub, if the egr is bad should the stick or should it not stop the codes from setting even with the bad valve?
