**** Assume nothing!
Is this an intermittant problem? Does the car ever start ok? Under what
Vacuum leak that closes after a warmup?
Have you checked your plugs? Lean or rich mixture?
Try spraying starter fluid thru one of those bonnet yellow plugged nipples
while the engine is running rough. If it clears up, then its a fuel related
Propane can be used also.
You want to isolate the problem to either fuel or ignition system.
How old are the ignition parts? cap, wiring, plugs? If these are due for a
change, change them now and remove that area from suspicion.
I see you have a turbo. Thats a bit out of my league. Turbo engines have a
host of other issues to check out, most having to do with vacuum leaks.
