I took my car down for inspection and it failed nox just slightly.
I ran codes and got 33...egr valve not opening/insuficientf flow and 49...default spark error. Is it likely that the faulty egr is causing the default spark code? I've done some searches on here but I'm really not sure what to look into first or how. Plug, plug wires, and o2's are new. The cam sensor, dis, and crank sensor are not too old and seem to be working fine.
I'm not too familiar with egr so any explaination of that system would be great!
