I got your PM mate, I'm chewing on it!!

Although to be honest, in terms of my own car, I'd rather stick with a 4 pot, on the basis that I'm poor and that I'd rather have an SGI gas kit than an SPI one.

Good point, underpowered as they are. Good on MPG. Was comparing it against the Senator on the way back to uni, reset the mpg leaving home, went via a m8's and on to uni, set cruise at 70 , averaged 37.9  

That other car would be ripe for breaking  

I think yours has LPG already Tunnie - 37.9 at 70 - I get 31/32 if I'm lucky

Way way way way too low on a run for a 4 pot.

I know!   And thats on Shell Optimax   MAF was faulty and replaced but MPG not changed, fitted new fuel filter, cleaned out breathers,tyres 30 PSI all round.... any suggestions  :-/

a v6?

I meant helpful suggestions  

Reset the fuel comp when you leave home, do a motorway run....

I put the fuel comp to instant readout on the motorway, on a flat stretch of the M40 i easily see 40 mpg on the instant readout @ 70, even at 80 with the cruise on a flat stretch it will still read 38...

Many times I have reset the gauge leaving home which is Brackley, then a 15 mile country run (pulling out on T junctions) to a village called Chacombe, then its a 65 mile ish blast down the M40 and I go down the M4 into Hayes.

On a run like that I quite easily get mid 30's on a run... but as soon as i start doing town runs it falls dramatically, into low 30's high 20's...

Lowest ever i have seen on the average reading is 28 from lots of runs to a local town.

Back to the fault codes....

Is the 19 code normal with the engine not running, or not?

Certainly not on V6, I imagine 4 pot the same.  On V6, it means its seen the signal on this start, but then can't make sense of it...

So that means, that there is a good likelyhood, that the crank sensor is the cause of the bad mis-firing?

I can only go by my own experience. When mine failed, the engine cut. No misfire.

[JamesV6CDX]

Hrmmm. This one is starting, but missing on one cyl, and often cutting out at idle.

Think I need more investigation and a compression test

[JamesV6CDX]

Given that the coolant pressured (IMHO) too much for a short time of running, I saw a bit of sludge on the stick (only a bit) and that it's missing....

Could this be a HG issue?

[JamesV6CDX]

If so, could change a HG on one of those very easily now

[Admin]

Well a blown HG will certainly cause some bad running...

But first things first.

Cam timing check then a compression test.

My cranksensor has a dicky cable and it was hard to start, ran perfectly at over 600rpm but kept cutting out at normal idle of 500. When it was at 600 if I stamped the throttle it would pop a bit before acce;erating. I had code 19 logged so checked what type of plug I had and in doing so I moved the cable. Since then it's started perfectly, idles at 500 and accelerates straight away when stamping the throttle. The new sensor arrived this morning and I shall fit it before the car goes on the road. For me a code 19 means a new sensor and I'd do that before looking anywhere else. You could try moving the cable though, it might fix it temporarily or kill it totally.

First jobs on my list

[Martin_1962]

Any luck James?

[JamesV6CDX]

I'm on nights matey, got called into work.

Unfortunately I won't be able to get my hands on it until monday lunchtime

[TheBoy]

btw, compression tester posted yesterday, so should be with you mon/tue...
