I'm hoping for some guidance on where to go from here. I've got 147k on my 03 Protg5, and a month or two ago I started getting these same 2 codes. Always both, never one at a time. P2009 is Fuel Pressure Regulator 1 Control Circuit and P0090 is Intake Manifold Runner Control Circuit Low Bank 1. Here's the run down of symptoms I've been having.
The past day or two it's had a rough cold start. It'll shake just a bit and give me high rpms but if I give it a few seconds it'll calm down and drive fine.
Occasionally if I hit the gas my engine will stutter and buck like it's going to stall. When I first noticed it I was afraid it was something with my transmission but it happens in every gear and I think it's more likely that it could be fuel starvation.
If I'm idling I'll occasionally feel a stutter in the engine, maybe a misfire but I don't get a code for a misfire when it happens. Almost feels like a compressor kicking on.Sometimes it won't happen at all, sometimes it'll happen every 10-20 seconds. I don't notice it at all if I'm driving.
I haven't had any loss in fuel effeciency that I've noticed. I've only had the car for a handful of months but I'm getting around 31.5mpg on average on my daily commute per the Bluetooth OBD2 scanner I use in addition to the Torque Pro app.
I flushed my Coolant last week and I noticed an electronic click noise coming from the engine bay, every minute or two it seemed, just one click that sounded like maybe a short. I couldn't find the source of the noise but it seemed like it was coming from the passenger side, closer to the firewall.
This may be related in part to the performance issues I've been having but I don't think it's the cause for the CEL, but the rubber tube coupler holding the aftermarket cold air intake is old and cracking. I've bought 2 replacements so far buy neither of them fit, the CAI was on the car when I bought it so I don't know the exact specs.
I really hope you guys have a clue on where to go from here short of testing every piece of wiring I can find.
