Help needed with power loss
Hi guys,
I’m wondering if anyone can add some suggestions for me...
1998 P38 4.6
For the last year it’s been missing/losing power above 2500rpm. I was hoping it would get worse to make it easier to diagnose, but it hasn’t.
Most noticeable cruising on the freeway at 110, the tachometer needle starts dancing erratically with slight power loss (about 2500rpm) if I start to put my foot down further it develops a bit of a shudder, then by the time I have my foot on the floor it really carries on, missing and I can’t get the revs above 3000 with complete power loss.
I’ve plugged in the Nanocom and the fault is “0340 camshaft position circuit malfunction” if I clear it, it doesn’t come back until I get it to start missing etc..
Here’s what I’ve done...
New spark plugs and leads
New fuel filter
Tried another MAF with no change
Removed and inspected the camshaft and crankshaft sensors (both looked ok)
I guess the obvious is to buy a camshaft sensor, but just thought I’d ask on here for any advice before I start throwing parts at it.
