Wrx problems. Need help

**mbfinatic** · 11-19-2011 07:04 AM

Hi everyone,

My dad just bought a wrx for himself. Its a 2006 and has about 73k on it. He was told it has some mods by the previous owner but it doesnt seem like anything crazy (Im not that familar with these cars). I do see a sti intercooler, boost gauge, straight piped. When we start to give it 75% throttle the check engine light flashes? Anyone have this problem before? If anyone could help that would be greatly appreciated.

Thanks in advance.

Do you lose any power when the check engine light comes on? When I got my 05 STi and gave it full throttle the check engine light would come on and I would lose power. Come to find out the peddle stop had come off my throttle. I would check that to see if it is loose or missing.

When you say straight piped, does that mean the exhaust from the turbo back?

I will double check on power loss but I dont think so.

Just under the car I didnt see a cat or resonator. It still has the stock muffler though.

if there is no cat, even if it has the stock muffler, it probably has an aftermarket downpipe which HAS to be tuned for.

^^^ make sure ASAP! My guess is the CEL is bc of this as well. Which means he needs to contact the previous owner ASAP!

Well now the check engine light is always on if we are cruising or giving it more throttle.. I checked and we have a bad battery. I think its more to that though.

I would still find out about the tune and exhaust.... A bad battery (I don't think) would cause the CEL to come on only when approaching WOT.

How do you remove the shift knob on this 06 wrx?

pull down on the boot where it fits to the knob, and hold it. and twist the knob. a lot. It will pop right off.

warning... my stock shift was easy to get out. My kartboy short-throw was a bear to get back into the socket. I felt like I was having to force way to hard.
