Hello all, I have been having an issue with my speed for a while now and I think I may have found the cause finally but would like to hear what more experienced members might think. Everything went south last winter when I installed my intake system, I had broken the elbow connector I needed to connect the valve breather hose to the intake. Needed to drive the car back to college and after talking to multiple people decided I'd get there fine since it could still "breathe" and I put a cork in the intake to stop it from sucking in there. I did end up getting a running lean code right as I got there after about an hour drive but the car seemed to drive fine. Drove back home the next weekend, and fabricated a solid connection with a similar elbow off another Mazda (I did have to modify it to fit the intake but 99% sure there is no leak here). Everything seemed good, but ever since then I have begun to develop worse issues idling and hard starting began to happen most recently. I have used the soapy water method to check for leaks and found none but re installed anything I had put on just incase, I also noticed my MAF will read weird by dipping down into the 2's and up to the 5's at idle. Most of the time it reads around 4 though, same with the fuel trims, they only go wonky when it begins idling poorly. My conclusion is that in the short time I had the valve cover breather exposed to the outside air instead of the air from the intake (plus the intake not creating vacuum which I did not consider at the time) enough gunk could have accumulated to clog the PCV valve and cause issues? I'm also unsure of if a bad/slightly clogged PCV would mess with the MAF readings like that? Like maybe its expecting the air to come in the intake from the PCV system and its not, idk. I plan on meeting up with another speed owner asap to swap his MAF to my car and see if it ends up just being that, but I doubt I'll be that lucky.
Considering this started after the intake specifically I'd assume its not related to my other mods, and I'm sure I need to add it to my profile but my total mod list is: HPFP, SRI, TIP, CPE TMIC. On cobb stage 1+sf tune as my full plans are to get a test pipe and then proper tune, however I'm really trying to solve this before spending more money on mods.
