Losing power on LPG

<< < (3/7) > >>

JumboBeef:
Thanks!  How can I tell if the coil is on the way out?

Range Rover Blues:
a) Gunson't flashtester
b) try a spare one for a few days

JumboBeef:
Ok, thanks.  I will try plugs and leads first (they always seem to be the trouble makers!)

JumboBeef:
This is what happened today.

Changed the leads: took it out for a drive, no difference.  Would not pull away but would tickover and rev.

Changed the plugs: took it out for a drive, no difference.  However, I limped a bit further.  After a couple of minutes, I could drive up to 2,000 revs before it would loose power.  Another couple of minutes, I could get it up to 3,000.  Long story short, after about 15 minutes of stop/starting/hard driving, it cleared and now drives as it should.

 :huh:

One of the plugs that came out was brown and looked old and dry, the others were normal black(ish) and slightly oily.  They were the wrong type (with an R).  It has always driven OK on petrol.

So, it is sorted.  But will it stay sorted?  :huh:

Range Rover Blues:
Sounds like a blockage then.  The 'R'simply means resisted, to supress radio interference.  You don't need it with good silicone leads and the resister just saps a little spark power.

A car that runs well should be ok with resisted plugs but if you are having trouble then fit non-resisted.

I use Iridium plugs and have no choice about the resister.
