Hi, hope someone on here can help.

I have a 2007 mcs. It went off the road 2 years ago due to the garage diagnosing a stretched timing chain. It’s been lying up my driveway ever since.

I finally got round to replacing the timing chain over Easter. Had a broken water pump drive friction wheel which stopped me getting it all back together. Part finally arrived so this weekend, engine is back together, sump was dropped and cleaned out, fresh oil and filter done.

Moment of truth...took a wee while to start, but then it has been sitting for 2 years.

It’s running beautifully at 2000 rpm, but lift your foot of the throttle and it splutters and conks out.

The timing is absolutely spot on...I checked it over and over.

Could it be the vanos solenoid that’s causing it?
Any other things to check?
No check engine lights came on. I don’t have a code reader to check if there are any being reported.

Any ideas gratefully received.

Thank you.

Garry
