I own an Evo 5. I just sent it for a tune up and got it back. The car keeps stalling when I am in traffic. And it doesn't pull like normal. I have a feeling they put in a regular lancer gas filter. Would this cause the problem? What filter should I use cause around here there are no Evos? I was told the V6 monteros use the same gas filter, is that true? Help me out ya'll!!!

 

Hmm, according to the evo service manual the only fuel filters are intank. There is one on each side. The non pump side has a filter on the pickup tube while the pump side has one directly on the pump. I wouldnt think these could cause your problems since they are not very restrictive in nature to begin with(plastic screens instead of paper). Try checking for vacuum leaks first.

 

vaccum leak?

 

I think it's either something to do with the airflow sensors, or if you have adjustable cams, and they touched something there. Have you asked them or have a breakdown of everything they touched. Might be easier to trace then.
