Merry Christmas.Allright gents, thank you again for the tips! Knock sensors it is, and I'll also replace everything in sight on the way down as necessary. I'll let you guys know how it all pans out. Probably won't be done before the holidays though, so Merry Passover and a Happy Summer Solstice
The whine from the power steering could just be air getting into the system.Hey all, its been a while but I finally got everything sorted. Turns out your gut instincts were right: it was the pedal pot. Despite being wireless and relatively new it had a microfracture in the casing that borked the pot. I got a new one and after resetting the rev issues were gone.
On the way I also replaced the knock sensors, cleaned out the V, replaced the air intake piping and hoses where I could, and she is now purring like the pretty black kitten she is =) My only remaining issue is a whine when I turn the steering which is probably either steering oil too low or the power steering pump acting up. I'll look into that next.
At any rate, a huge thank you to all of you who spent your time providing me with pointers! Hopefully I can help someone out in turn in due course
Hi Dave,Hi McAnix so my sensor had a crack in the sensor body? Any chance you could send that back to me so I can see what went wrong? or a photo perhaps? I don't see many failures really do you think its been hit with something? Also its possible I could have just replaced the broken bit of it, I have quite a collection of parts these days.
I had some of these kind of problems on my old 2009 QP 4.7 S. Turns out it was one of the ignitor coils which was goosed and fortunately for me, it was on one of the cylinders I could easily access by removing a few things. Took me 30 minutes to replace with a new one (£105 each!) and reassemble everything. Surprise surprise that fixed it so all I had to do was clear the error codes.Hi all!
My 3200GT is acting up a bit so I'm trying to work out what is wrong, and hope you guys are willing to have a quick look at my errors =)
My woes started with intermittently going into Limp Mode; I wouldn't be able to get it over 120kph even if the wind were right. This problem went away for a while after I had flushed the oil (it was a few months after I had bought it, and figured that even though the previous owner was knowledgeable, I figured it couldn't hurt.)
Now however it's back with a vengeance, and it comes combined with rev issues. I had that before once, but was able to fix that with the throttle reset trick. Now, I've tried that several times but no cigar. The car sometimes goes into limp mode, but on the other hand sometimes it keeps trying to rev up to 3-4k (it varies, sometimes it wants to rev far higher than other times, which lead me to suspect electronics.)
I have bought and hooked up an ODB reader and read out the error codes. Here's what showed up:
P0150, 02 Sensor Circuit Malfunction (Bank 2 sensor 1)
P0110, Intake air temperature circuit malfunction
P0325, Knock Sensor 1 Circuit Malfunction (Bank 1 or single sensor)
P0330, Knock Sensor 2 Circuit Malfunction (Bank 2)
P0352, Ignition Coil B Primary/Secondary Circuit Malfunction
P0354, Ignition Coil D Primary/Secondary Circuit Malfunction
P0355, Ignition Coil E Primary/Secondary Circuit Malfunction
P0356, Ignition Coil F Primary/Secondary Circuit Malfunction
0x1172 Unknown code (googled it and found it is related to the Lambda Sensor?)
P0225, Throttle/Petal Position Sensor/Switch C Circuit Malfunction
Note that the engine idles and runs fine when it's not in limp mode or in one of its "bad rev" phases - no misfires, fine idling (though it does seem to "breathe", i.e. slight ups/downs idling, but as I understand it that's normal).
Also, the previous owner replaced the throttle with a wireless version so that "shouldn't" (famous last words, but I have the invoice ) be the issue.
Finally, I must shamefully admit to having hitherto used standard supermarket fuel. I thought I had read up sufficiently, but apparently not. After leafing through the forums I'm already convinced. I'll swap to V-Power or similar.
Now my amateur sleuthing skills have me seeing primarily electrical problems here. Am I guessing correctly that the primary suspects are the lambda sensors, and secondary are wiring or something? Or should I look at the sparkies / coils first?
Thank you for your time =)
