Not yet, but I did think about it. However, 3 MAF's can't all be wrong surely? The original and two (new) Bosch ones
from same indy dealer...
It has been suggested I have a leak, which I did have, but I found it and fixed it (I even reported it on here if I recall correctly) That was the stupid connection from/to the Idle Control Valve because some clown at LR thought a wrist watch shaped clip and a circle of rubber was a great idea. But it wasn't, it was a sh
ite idea because it came loose and the rubber ring piece wore away. My fix was to drill the hole bigger, insert the pipe from the inside and glued the lip with Tiger Seal. I "KNOW" it hasn't leaked since, mainly because it's super tight and besides, it's scared to leak again
I am not convinced I have another leak, although I won't rule it out.
It has also been suggested the PCV is choked, which is also a possibility because the rockers do weep, even though I replaced the left one. But I am at a loss as to how would a PCV block on an engine that has covered only 19k miles. That's right, nineteen thousand miles is nothing!
The only thing I can think is a slight possibility is that it may have got blocked by sitting for 5yrs, but then it had barely covered 2000 miles at the time it was parked (I have every service schedule and invoice as well as word direct from the man who installed the engine under warranty) and the 1st thing I did upon buying the car was a huge service inc oil & filters. You all know I have treated this car like a princess & the oil gets changed around every 6000 miles so it's had 3 changes and is due another.
I am liking the PCV idea, but not convinced. The other suggestion was a (slightly) blocked cat, but again I'm not convinced because this car just doesn't run rich in general, especially with the LPG system doing 80% of the fueling
The cat "issue" is an easy fix by removing and putting straight through pipes in. But while the torque (and noise) will increase, who's to say it would cure the hesitation?
Then there is the TPS, but again, the code reader (which is a proper job worth thousands of pounds and the local dealership comes to him for code reading, not to mention he knows exactly how to use this device, it's his bread & butter) said only MAF problem.
So how do I go about convincing him to do a live data while driving around and wouldn't this device flag up the TPS as faulty? It found the O2 sensors are great, no plug, lead or coils issues flagged up (except when I pulled a plug lead off)????
If I knew what to expect on which wire at the MAF plug then I could use my digital meter to read any signal along those wires.
Apart from this, the engine can sit for weeks at a time and fire up first turn of the key. It idles beautifully and at full chat the car flies. I can go up Drumossie at 90mph (ahem, should I wish to
) so power is there.
To me, it feels like if it had a distributor, that it was worn, so the spark timing wobbled upon throttle demand! If on hard acceleration, it does what you ask. On gentle first push on the pedal, I get this hesitation....
