I posted up a while back about a cold start issue I had when running 93 octane... I would have to crank the engine 2-3 times for it to actually start... Well, today with 25 degree weather, I had to crank it 5 times, it would start, then stall about 5 seconds later... Crank another 3-4 times and each time it would start for 5 seconds then die... Thing is, I am now using 91 octane and it is still doing it... MAF is good and compression is good... Plugs are also somewhat new and correctly gapped since 1 month ago... Any ideas?

I would like to know this too, mines starting up but dying immediately, the temp here is 5-10 degrees lately...

perform an engine decarb using BG engine clean, change the oil and possibly put in a new ECT

I do that every two oil changes... Can try the new ECT though...

It could be a coolant temp sensor. Mine did that because it couldn't figure out whether it should do a hot or cold start routine.

Yeah, I am trying out a new CTS from Komp... Worth a try for $13 I guess... And also, just wait until tomorrow... [;)]

When would I pull them? Before I start it in the mornings? They are BKR6E or whatever... Coppers with a 6 heat range...

i would try before and after starting. if they are wet before start then they aren't burning everything. same goes for after running the engine. clean them off, with a sand blaster/spark plug cleaner. put them in and try again. if it kind of runs a little long or better then it's definantly spark plugs at fault

Or I could just buy new ones for $4
