I need a little help. My truck won't idle. Iv replaced plugs, plug wires, did a spark test, tested all injectors, replaced idle air control valve, and it still won't run. It starts if it has sat for a few hours, but it won't idle. And once it dies it won't start again. It makes a loud sucking sound. It's a 98 ram. 318. I don't get around a computer very often so if someone could text me or call me and give me some direction it would be very appreciated. 760 793 6979. If I don't answer leave a voicemail. Thank you.
