Here recently my car has been feeling extra sluggish more so then normal. Well as of lately it started what felt like a misfire every now and then only under load. The car currently has no power what so ever.. literally like no power under load I cant speed up hardly to get around someone now.
I've replaced, plugs, wires, and coil pack yet the issues still occurs. The car idles fine and I can rev it no problem. However I cant accelerate worth a fuck due to this misfire/stumble/no power issue. Even if I roll onto the throttle you can feel the car bog down right before its going to stumble and misfire. It does not do it to the point that it throws a CEL which is the weird part.
Now I can cruise down the road without issue its just trying to accelerate that I have an issue with. I was told to remove the vac line adn plug it off the FPR and see if that made any difference and it did not. Also the car still sounds the same while running with the MAF disconnected and still revs fine.
I'm currently trying to get a hold of one of the local MSPer's to see if I can switch MAFs for a few min just to see if that is my issue or not. I also hear that it could also be the TPS and or the IAC. However I have no ways of testing those and no CELs on the car currently.
Edit: Another thing to note is that it really seems to be a load issue. Every time the car gets around -5 of the boost gauge it bogs and acts up.
