So this is my first post and I need help bad lol

HELP FROM TRUE ROTARY GURUS! This car is lucky it's fun to drive for the most part... Otherwise it would have been gone months ago. I'm having codes pop up like it's Christmas lol. I tried everything and I'm officially stumped... So it started off going into limp mode a month ago, reading P2012(throttle body circuit low). Now it's spitting out codes like P0032, P2270 and P0139. It's a new core, 12ks on it and 30kms coils, plugs and wires. Symptoms are small percentage power drop across full rpms, will feel like total spark cut sometimes for a split second, will go into limp mode every 15 mins or go 4-5 days with nothing throwing code P2012.

Already tried: MAF sensor cleaning, throttle body disassemble and Cleaning, K&n filter cleaning, red line through all gears to burn off any crap that may have built up. So for nothing.

Would really appreciate the wealth of knowledge and input that's in this group.

If those are the codes you're getting then you probably need new O2 sensors all around.

Its disconcertingly obvious actually (but not necessarily your only problem).

If the voltage don't move then replace the sensors. the pre sensors are easy to get to. You may need o2 sensor socket.

check your wiring also leading up into the valve cover area.

Ok?

Post a picture of the valve cover area please

Codes: So new ppl reading thread don't have to go look them up

P0032 - Front HO2S heater control circuit high
P0139 - Rear HO2S circuit slow response
P2012 - P2012 Intake Manifold Runner Ctrl Circ Low Bank2 >>>>> http://www.obd-codes.com/trouble_codes/ (So take it for what it's worth because it didn't come from the forums SI WSM)
P2270 - Rear HO2S signal stuck lean

It's right behind the timing chain. Geez. Search, newb!

All the other codes other than p2012 seem to be o2 sensor related. But thats most important one which is causing my car to go into limp mode every 15-20 minutes of driving, and I can't seem to figure out the exact area of issue. I rear something about either a sensor or actuator controlling the flow and pitch of air going into the combustion chamber in the intake Manifold?

That's right, I'm not familiar with that code, but it could be the SSV or VDI sticking in some way.

So how would I search for this code on this forum? I've searched it and cane up with nothing so far.. Ill be posting this same thread in trouble shooting series 1 once I've hit the "10 post level' lol

You'll get in poo-poo for double posting.
And it's better to keep it all in one thread.

Tech info:

P0661 - SSV solenoid valve control circuit low
P0662 - SSV solenoid valve control circuit high
P2070 - SSV stuck open

IMO best way to search forum is using Google like this (not including quotes)
