Hi all,

I have been using this forum heaps since acquiring my car, it was from here that I was able to work out that my plugs were wrongly gapped and fixed a miss under boost, so thanks!

Here are my problems
My car is isn't starting in the morning without blipping the accelerator.
It farts and pops and is very unresponsive at around 2500-3000 when cold, when hot its fine.
It idles slightly high, around 1050.

I have fists of ham so I think I may have knocked a vacum line when changing my oil filter??

Anyway, any ideas before I start touching s*** I really shouldnt!! I am trying to load a youtube video of the failing start will add if I can get it going

Cheers in advance!

Idk why but your video says its restricted. anyways, usually the first 2 things I do with cold start issues is check for 12v at the start signal write to the ecu when cranking the starter. The other thing I would check is the coolant temp sensor.
