Knowledgable truck guys....
...my truck doesnt like to start when its cold...its a 2001 chevy silverado 2500....when i turn the key i have to hold my foot on the gas and the brake and rev it alot and keep it at 1000 RPM to keep it alive and also to shift and when i slow down or get under 500 RPM it dies...what could cause this?? it also sometimes doesnt start when its warm every once in awhile but when it does it atleast idles...but in the cold it doesnt even idle....ideas!?
