Very Porly 600

Hi,

I was driving my 620sli (Honda engine) the other night along a dual carriageway all was fine until I went to stop at a roundabout when it died and wouldn't restart. The engine was very hot although didn't show on temp gauge. I towed the car home and tried to start and it did straight away as usual.I have since sorted the cooling problem but have a serious loss of power. i.e. when engine on idle all is fine but when I rev the engine for a while (at standstill) then release power it will not go back to idle and just cuts out.

I have flushed cooling and oil systems and done a compression test and all ok and i am now at a loss of where to look now. Also the fuel supply seems to be ok.

Anyone have any thoughts?
Any suggestions will be greatly appreciated.

Can you give more info :

Mileage on engine
Any past issues ie how long have you had car , has it done this before ?
What cooling problem have you sorted out ?
Did you drain off as much oil / water at expected ?


What state are the plugs ? (ie golden brown as expected, all the same colour ? ?)
Diz cap / rotor ok ? (mine cracked at 130k - although didn't cause this)


if those ok .. -- then to failed sensor - maybe Temp sensor into ECU (ie not the gauge one)

I assume no engine check light.

All sensors ok

Did you check for any stored fault codes?

Locate the diagnostic plug in the passenger footwell, bridge the connector with a paper clip, turn the ignition to on (not start), if there is a fault stored the code will be displayed as a series of long and short flashes via the check engine light, 1 long = 10, 1 short = 1, get the code and post it here.

Hi gordon and Ray

Have checked for fault codes and there is none.

Since last post i have changed the fuel filter and checked the pump works ok.
Also i have cleaned the injectors, rail etc. and cleaned the air system.
