:iagree: I'm constantly gone and every one else is busy. The whole forum in general is going down hill.

This is very true!

How long was your install and whats the difficulty on a 1-5 scale?

Agreed. Its had its time. LoL. Let it enjoy it's days in the pasture until it's too feeble to walk and lays down alone in a cave somewhere... Or...OR..we can tell it to look at the flowers and put one between the ears... LOL

The forum may die but the pleasure I have when driving my car won't.

So just threw a service engine soon light last night.

I heard its usually in junction with Emissions and ****.

I havent gotten a tune after the intakes, hfc, and exhuast so im sure thats what it is

Especially since i smell gas everytime i drive since for a few months now

Which HFCs are you running? Do the have the extended O2 sensor bungs? I did get your text and responded but I'm in Japan right now and texts to the US aren't that reliable for some reason.

Thanks, and unless they came with the stillen HFcs then no extendors.

I knew the air to fuel ratio was off months ago when i first got the hfc, intake and exhuast installed (on the same day)

Cuz i could smell gas when starting it up... i had thr shop recheck the exhuast to make sure no leaks... figured it was halfway normal since driving behind test pipes smells horrible

I know i need a tune but thats weeks away, if even. But i am gonna stop by autozone latta see if they can tell me what code

So error code P0420

Description says the Bank 1 Catalyst system efficiency was below threshold for a predetermined period of time.

it took about 8-10 hours (i took several breaks)... i can probably do it quicker since I was learning as i go... I ran front and rear cameras... i rate it a 3... you got to know how to use a multimeter, run wires (from the engine to the unit), and be comfortable with drilling into your front bumper...

It is time for me to get new tires. I hate when I floor it between 1st to 3rd gear and my car is sliding sideways (backend pulls right) on the road. I wanted to pick up some Michelin Super Sports since they are on sale on TireRack for $1060 shipped (245/275), but I'm worried about the weather here. My other option is BFGoodrich GE-Force Comp-2 AS for $820 (great reviews and my brother has them on his Z and swears by it).

If I get the BFGoodrich I can pick up sway bars or the RJM pedals. What should I do?

Or Pilot Sport A/S 3+ for $944

You know my answer.. bridgestone pole position ����

This is what I prefer;
Yokohama ADVAN Neova AD08R tires for the warmer months and track days.
Continential ExtremeContact DWS tires for the colder months.
:twocents:

If I was DD'n my Z, I would run different summer tires.
