ppe uel with the wires supplied with kit
breather kit to atmosphere
rr tune ( this got rid of all previous cel associated )

These two came up at random after having been trouble free for about couple months

p050b does have odd idle at start as suggest
p1170 not sure

is it possible that because I didn’t use vacuum plugs on the intake arm? It’s a bicycle tube that I cut and zipped on. Been trouble free until now


off tangent question: RR coilovers and street version LCA bushings. Over harsh bumps feels like no bump stops/about to explode. Is it the LCA bushings or the coilovers? or both. It's harsher than my race car that has SOLID bushings or urethane injected bushings all around.

 

According to Alldata: DTC P1170 - Port Injector Fuel Performance
Give RR Racing a call

 

I called, I was told to check the 02 wiring for the p1170 and they've not heard of the p050b but advised to clear it and see if it comes back.

I will check them out

 

That's not much to go on. There's a lot more to this on alldata diy.
