Cut off

[The Devils Own Chariot]

Hey guys. I installed a cone air filter in the Sy and left the hose that connects to the air box off. I was driving it around a little bit after wards. When I hit like 85 - 90 I get what seems to me like fuel cut off. The engine light comes on periodically then goes away. I was wondering if not having that vacuum hose connected so its not seeing boost would have that sort of effect? I also noticed that my intercooler was too hot to touch. I assume my intercooler pump is out. Where can I pick one up? Oh and I don’t have a datamaster yet but plan on it. Can you guys help me ?

Re: Cut off

... what mods have been made ???
sounds kinda overboost to me (search that :tup: )

regarding to your IC-pump : http://www.sytyarchives.com/howto/viewarticle.php?article_name=ic_hose_and_pump.php&dir=engine (look @ "parts")

also check : http://www.sytyarchives.com/howto/viewarticle.php?article_name=ic_pump_diagnosis.php&dir=engine

if ok, then i suggest a hotwire for the pump : http://www.sytyarchives.com/howto/viewarticle.php?article_name=ic_pump_hotwire.php&dir=engine

The hose that connects to the stock air intake track that runs under the upper ic is for the pcv and wouldn't cause stumbling or error codes.. I would have to agree with dirtdemon about it being "overboost" which would cause a stumble and an error to help prevent you from grenading your motor.

I would get yourself a paper clip and follow this http://www.sportmachines.com/maintenance/aldl.php and see what error code was set and go from there... also if your upper ic is hot then I'd test to see if the ic pump is getting power and if it is but isn't running.. replace it before getting into the throttle again.

Re: Cut off

Oh and reguarling what you said about the intake vaccum hose. The hose Im talking about goes to the valve cover Im pretty sure. Is that the same one your talking about? I know what hose you are taking about. There is another one that goes under the IC. Im looking at my Chilton manual and it shows it as a CCV (air out). Would that have any effect?
