Its been running perfectly, up until about 10 days ago, when I noticed a stutter after starting (when the weather changed and got warmer), and the idle has become a bit rough at times. Not always, most of the time its fine, but every now and then it drops from 750/800rpm down to 500rpm then up to 900 rpm, then back to a smooth idle.

Didn't think anything of it, just accepted that old cars get like that (its done over 300k miles), and I could live with it.

Until today.

Now its stalling on me. Not all the time, but it's happened 5 times this afternoon. Always starts again, but its also beginning to run poorly under load. Again its intermittent, like the odd cough every few minutes.

I've got a Peake code reader, so ran the codes this afternoon and got:
3505 - glow device
0480 - electric fan
1A04 - coolant temperature heater
1E30 - air pressure control or charge-air pressure actuator

I was expecting to see a cam sensor fault, as Google suggests that this is a common fault and cause of stalling, but now I'm kinda left scratching my head as to what to look at to sort this out.

Thoughts and suggestions gratefully received.

Anyone??

Also got another code today after it cut out on the M6 - 1190 pressure plausibility.

Don't want to throw money at what is effectively a shed, but happy to get my hands dirty...

Should I be looking at EGR valve, tank pump etc...?

Have you changed your 'stats and crankcase breather??

Check the temps in the hidden menus and see what you are getting to.

Also, the crankcase breathers are notorious for failing, meant to be changed every 3 oil changes, but many have never been changed from new.

It's a fuel rail pressure problem, starting with a new filter, then see where it goes. EGR was fine, MAF was fine...
