2005 Saab 9-3 Linear
 

hello everyone, I am new to this forum. I have a 2005 9-3 Linear. I added a K&N Cold Air Intake Kit to the car and it caused the engine light to come on. I believe it is from the hot air that gets trapped in the engine compartment when I am stopped at a light or stop sign. When I start moving again, the car is very sluggish and the turbo will not spool until the air starts to flow in.

Any ideas on correcting this problem?

Can you show me a picture of the setup? The problem may be a leak or some sort of problem with the MAF....pull the code too...

RE: 2005 Saab 9-3 Linear
 

I don't have the equipment to pull the code but here is a shot of the setup.

AutoZone will pull codes for free... if the code is related to the intake than it could be a leak somewhere after the MAF.

I need to get the car inspected this month so I put the air box back in. The light went back out in 2 days.

The light came on first after about 45 mins of driving with the new intake. If it were a leak, would it have come on sooner, maybe a 1/2 mile down the road?

I know, it's hard to speculate without the codes.

After I get the car inspected, I will re-install the intake. If the light comes back on I will get the code(s) and send to you.

I'm more than sure that it's a leak of some sort...one thing I can't see is the recirculation hose. Did you remove it or is it just out of sight?

RE: 2005 Saab 9-3 Linear
 

I took the picture right before I installed the hose, so that is why you do not see it.;)

RE: 2005 Saab 9-3 Linear
 

Did you run with the hose off? I think the problem is with the recirculation hose...I'd need to see how it's mounted to the K&N

RE: 2005 Saab 9-3 Linear
 

I disassembled everything to get the car inspected.


The instruction that came with the kit states to install the hose no more than 4 inches from the filter, I had it about 2 inches from the filter and feeding from the front grill.

RE: 2005 Saab 9-3 Linear
 

wait, what??? you mean the hose wasn't being directly recirculated into the intake?

RE: 2005 Saab 9-3 Linear
 

maybe we are talking about different hoses?

see here for the complete kit. I am talking about the long hose shown in the picture.

see here for the instructions, I followed them exactly.

RE: 2005 Saab 9-3 Linear
 

Yeah, we were talking about different hoses. I would say the CEL was still MAF related...must have been a leak right after it.

OK Roto, I finally got the car inspected, now I can get back to this.

I may have found the leak you were talking about. I was installing a Boost Gauge and noticed one of the vaccuum lines had a slice in it. I fixed it and I will see what happens once I re-install the intake.

about the boost gauge, I tapped into the vac line coming from the boost controller that runs to the turbo housing, I am reading 8-10lbs of boost but it does not register and VAC. Any ideas??

RE: 2005 Saab 9-3 Linear
 

I spoke to a guy that has had 7 Saabs. He stated that the Engine light was coming on due to the increase of air flowing to the turbo. The boost controller was confused thinking that the turbo was overboosting and would shut down.

He also said that I would have to get the car re-programed in order to compensate for this.

Do you think a manual boost controller would work without re-programming??

He also helped me with the boost gauge. We tapped into a vac line coming off the manifold instead of the turbo itself. It works great now.

i knew it would throw a code those KandN filters off ebay never work with the saab 93 03-06 neither do the blow off valves...check out bsr its expensive but they sell a chip that reprograms the car completely that will let you do mods to it...i had a BOV installed on my 03 93 and it threw a code and caused me more to fix it then to put it on...and the Saab dealership wouldnt adjust my computer in anyway to compensate for it

parts, tuning, and anything related to it- I'm interested in reading about it so please share.
