The new engine in "the pretty pig" outclassed an 80 series TD LC, GQ Petrol Patrol and 2 year old TD Navara on the weekend. After walking up the first muddy hill climb the others had just retreated from (up at Walhalla), we quickly went from being mocked to being used as the new bench mark. So much so that half way through the first day I heard the comment "if the Rangie's not going up then we're not even bothering to have a crack" (or words to that effect!)

Funniest thing was, just before we left off road "the pretty pig" started starving for fuel and cracking up at about 2500-2800 rpm. So the entire trip was done on the bottom end of the rev range! Still not completely sure why, but initially had thought it was bad fuel picked up in Moe just before heading for the hills. Upon return home changed fuel filter (to no effect) then on mechanics advice pulled MAP sensor and gave it a good clean (with CO Contact Cleaner) but again no change. Pulled MAP a second time to double check and it still looked really nice but noticed there was no O-ring between air box and MAP body (). Hence MAP may be getting mucked up... will get one in to her tomorrow and see if that fixes it.

However, I still can't understand how it can run like a treat for the first week or so and then just drop out like that... prior to the trip I was giving her the odd rev up toward the top end and although it wasn't ultra smooth, I thought she was going along quite nicely for a tight new engine (although we did have a bit of fuming here and there previously which strangely seems to have dissappeared again). Also, given the old mate who did the engine change must have left the O-ring out, I'm really stumped as to why all this would simply start a week or so later anyway?!?

Any of youz P38 GURU's got any experience, comments or suggestions about what else might be going on here? Could the break down be spark and not fuel/air related? Should I be getting diagnostic checks done? I have heard conflicting stories about MAP issues not even showing up on the various test equipment?!?

Does all this talking about it really help?!? - I think it does... Or, should I just go and get my head checked by a shrink for getting so intimate with the pretty pig (as Mrs sometimes reckons!)?

Anyway, would really appreciate your comments... Me a little lost again... but still pretty happy!!!

Hoo Roo, Dave & "the pretty pig"

I'm assuming the pretty pig is a P38???'try a new crank angle sensor. I had one go the other day which limited my revs to about 1800rpm.Other wise the car ran perfect. Regards Russell
