when I bought my typhoon it was in ST George so much warmer then were I am at in Layton Utah during the summer she runs great but as soon as the cold hits she doesn't want to run as soon as I hit ten pounds of boost she falls on her face she will sputter then back fire I was thinking that it was my MSD going bad but I had someone look at it and said that its not the MSD even in the summer if it rains she will act up and I'm still a some what beginner on working on cars but love doing it I have help my ex for 11 years so can you please help me and throw out you think could be wrong because once again during the summer I can hit twenty pounds of boost and she does it just fine
thanks

Re: sputtering problems

First to do check all ignition ground wires then
with engine running spray a fine mist of water
on the ignition wires to check for leaks this can
cause misfires at boost pressure did you service
the sparkplugs recently ??

Re: sputtering problems

I had the same exact problem from summer to winter. Ended up being that I had too much spark plug gap. .028 gap fixed it.

Stored truck for more than 2-3 mons? Did your gas spoil?

Not sure If it can be a problem. Investigate fuel pressure , pump prime, any suspect noises so on.

I run a blend of 100/93 in my syclone. the gas is guaranteed to be good for 90 says stored. I Just empty my syclone tank because I think I am going ti be storing it longer, and I filled my honda with a nice blend.

Could be a low octane issue. Or fuel related.

Re: sputtering problems

I will check the plugs too hopefully thats it something simple... the gas i put fuel stablizer in it to help it be ok i also just let it idle occasionally but if there isnt any salt on the ground ill drive it around so usually i can run the gas out and put new in .. i did think it was the fuel pressure that it wasnt getting enough gas so i turn it up but still didnt work i was told there is a sensor that tells it to give it more gas in the summer then the winter that it may be bad but what sensor is that??

Check the dizzy cap. Remove it and check for corrosion inside.
The pickups and all. I had a similar issue and this was where it stemmed from.
Good luck!
