Hello!

 

I have some problems (again!).

 

Same as I posted a month or so ago, still not got to the bottom of it.

 

When the car is cold, it runs pretty badly. Judders a lot under steady acceleration, but idles okay. As an example, if I'm driving along at 20mph, the car is juddering like hell, and when I come to a halt, it's fine. Idles okay, doesn't even attempt to cut out.

 

This happens all the time until the car is warm (temp gauge half way up). But, also doesn't happen for the first few minutes of driving. After the initial few minutes of a drive from cold it happens, not instant.

 

I plugged it into Conzult last week and it threw up Error Code 13, collant temp sensor, so I got me a new one of those fitted, now no error codes.

 

The car has recently undergone a full service, plugs, fuel filter, oil changed, collant changed, air filter changed etc etc.

 

Only thing that was noted during the service is that the collant expansion tank has been blocked off (no idea why!).

 

Could that be causing it? I'm going to fix that anyway.

 

But mainly after any other suggestions it could be??

 

Thanks for any help :D

Anyone?! :D

i had similar problems with dodgy coil pack connectors/wiring, once warmed up i assume the heat made the connection better, if i wiggled the wiring to the 2 nearest the radiator the engine would pick up straight away.

i had same sort of problem and my zed is really slow to start takes ages on turnover and i found out when i pressed the accelerator on start up it would run really rough till it got warm and with no accelerator it didnt play up at all may be something to look into.

Cheers for the replies chaps!! Will double check the coilpacks tonight!
