Engine Light Coming On...

[jase-r34]

I just recently had a full 3" exhaust system fitted to my r34 (turbo back) and since then the engine light has come on twice.

It only stays on for approx a minute or so then goes out again. Maybe just coincidence but it happened after approx 150km of driving after the exhaust was done and the second time was approx 150km after the first time.... only thing i can think of is maybe the O2 sensor or something? Has anyone experienced anything like this before???

Btw, Im new to the forum. Its great! have found heaps of useful info on here already!

egt sensor in the cat. have a look at it. they arent very gentle when installing stuff.

OK it's been about 250km's since the engine light has come on and now it is on and staying there.... the sensor in the exhaust looks to bi fitted ok and the wiring is connected and undamaged.

The only other mod i have done so far is a K&N panel filter. I was wondering if maybe the oil in the filter might be messing with the AFM? any thoughts?

Thanks for your help!

my cat sensor is going stupid since the hot wave of heat a couple weeks back. thinking of cutting the wire to shut the thing up!

Ive cleaned my AFM and refit the original air filter, light is gone and seems to be fine now! what a waste of money on the K&N!
