new CAI issues (too lean)
So i installed a Cold Air Intake(CPT) and a nice oiled filter + hydroshield(Injen), but after 5 hours of driving the car now continually trips the Check Engine Light saying my mixture is too lean.
I have researched a few things First thing it could be is It says maybe if the filter is over-oiled then it could gum up the MAF sensor so it should be cleaned. What would be the best way for going about cleaning the MAF sensor without risking damage to the sensor? Second thing it could be is It says it could be caused by a vacuum leak in the system, I have checked all my connections and they are sung with no apparent leaks. My brake booster however is shot and after purchasing a replacement from a scrapper i looked up how much of a pain it is to replace, being such a small car it does not really need the booster as I have been driving without it for at least 2 years now. I ran my little bluetooth scanner using torque on my phone and the vac pressure sits at about 25 idle, 15 cruising and can go as low as -1.5 under heavy acceleration. I have heard it should never drop below 1. Would there be an easy way to block off the hose to the brake booster or should i just take the whole day and rip apart my car to replace it and hope i do it properly? Car is still running okay and has a very nice front-end growl to it under acceleration which i like a lot, just annoying the CEL is coming on and I would like to get the issue addressed hopefully this week. I will be adding pictures possibly later today of the new intake |
