ok after i ran out of fuel last night my truck is running horrible...i figured that there was air in the system so i let it idle today for 20 mins.. ran worst....could i have a bad injector??and if it is where can i get the cheapest injectors maybe get stage ones idk i need it back any help please....

could be an injector...could be a fuel pump....and it could just need to be driven to get the air out of the system....just idling wont get the air out...

If driving it doesnt help....then you need to check fuel pressure......but drive it as hard as you can for about ten miles....see if that helps

i drove it around the block and it smoked white like no other....but you saying for about 10 mins ok ill try..but it feels like its running out after getting on it and then you can hear the injectors tapping....

if there is a bunch of air in the heads they will do that....try driving it....

[mschn99]
