Rough Idle Just Come on all of a sudden

[jonathanvb]

I pulled up my driveway, then put the car in reverse parked it where i wanted it and then it just started idling really rough, i started fine again straight after, put then about 10 - 15 minutes later it took alot of cranking to get the engine started. Does anyone have any ideas on what might be causing this?? Any help would be greatly appreciated.

It would be the CAS if the car is hard to start when the engine is hot.

check your fault codes firstly, it could also be a faulty IAC valve in the throttle body. possibly a crank angle sensor? but yeah check fault codes first.

CAS for sure, it does that sorta stuff!

i have checked my fault codes and it only comes up with 43 which is knock sensor is experiencing problems which has been coming up for a while and what I was going to do something about very soon. Could it be a cracked head or blown headgasket??

check spark plugs and leads and make sure there all on properly

I have checked the spark plugs and leads and they are all sweet, i have just started the engine again about 2 hours since i last started it and it started quick as and smooth as (just like it usually does), then went on and idled as it usally does nice and smooth, but there is still condensation coming out of the exaust (which i forgot to mention before sorry)

Any adavnces with this information

[SlowVac]

condensation from the exhaust means that the engine is tuned and there is nothing to be worried about unless its blowing blue or white smoke.

Just started my car up again this morning and started and ran mint as. If it was a blown head gasket or cracked head, it would be noticable even when the engine is cold??

Probably not the problem but good to look at. I found a faulty wire connection in the wiring loom near grommet in egine bay. The black and yellow wire splits off into 2 wires one of which goes to throttle body sensor.
When i would move the loom it would run rough as or even cut out. The wire only has tape around it and is only crimped instead of solder so it picked up moisture and corroded. Try moving the loom around while engine running smooth and see if problem starts. Easy way to test for head gasket problems is to take out your spark plugs one by one and check the colour of the tip(of the sparkplug). They should all be grey or have a tint of rusty colour. if you find any with moisture or darker colours then that cylender may be leaking. I know that mine is iffy on number 5 but its not causing to much probs yet. Only if i go on the beach.
