16v KR being hesitant under load once warmed up

[Martin_B 10]

As per above really, over the last few weeks i've noticed my corrado struggling when warm. Car feels really jerky whilst accelerating.

 

I haven't done anything to the engine since I purchased the car apart from fitting a K&N panel filter about 3 weeks ago.

 

Does anyone have a checklist of things that I can go over to try and troubleshoot the problem?

 

Thanks

Check for vacuum leaks. The corrugated section just before the throttle body is guilty of cracking at the bottom of the corrugations. Or it may be an engine mount going.

It being a K-Jet - I would think that might be fuelling issue.

 

Maybe this will help.

Checked the HT leads just now, one of the electrodes was/is stuck in the distributor cap. This will most certainly contribute towards the hesitancy whilst accelerating?
