Cylinder 4 running slightly lean?


Recommended Posts

Hey guys want some input was going to get a tune from infamous1 but I feel fixing this lean condition might be important. I did my spark plugs and noticed cylinder 4 (driver side closest to the firewall) appeared to be white, noticeably more white than the other 3. What bothers me is there is no damn fuel filter! So is it possible debree got to that injector ? Thinking a bottle of fuel injection cleaner won't cut it.

I'd spend the $10.00 on a can of injector cleaner first. If it get's better you've fixed a simple problem.

 

Does the car run badly ?

 

I'm guessing you haven't had a CEL's.

 

Have you sent a data log to Infamous ? My Tuner is a bit closer to you. http://www.tuningalliance.com he can help you too.

Hey, it runs pretty good, but i feel when I floor it doesn't pull as hard especially up top. Doesn't really feel as smooth when I floor it as well. Otherwise idles mostly fine and drives around mostly find but there isn't alot of power maintaining speed up inclines. Going to try some injector cleaner thanks!

Also make sure the tmic is not leaking. They have a habit of doing that. I'm not sure what could cause #4 to be lean other then a dirty injector.

 

I guess you have checked everything under the hood to make sure all is normal and correct.

 

It has been said that these things feel stronger at 3/4 throttle then wot.

Do you have aftermarket injectors? There have been times when the injector gets stuck in one position or another. Injector is the cheap way to see if something is just clogged and Subarus have the usual pump filter and I have yet to see one fail.

If your going to get a Tune anyway's your better off to go with a after market full Al tmic.

 

I have a IPR on my 05. Like a lot of the after market one's it was a PITA to get on the first time. I've had it off/on 3 or 4 times now and it's like oem.

 

IMO I would never buy a OEM tmic.
