My Astro "Chug's" when it idles (say when it's in park or when I'm at a red light). I'm sure you know what I mean, but I'll try to describe as best I can. You know how motorcycles "Chug" (Ch-chuga-ch-chuga) and they're supposed to right? I'll assume my van shouldn't. What does that mean if it does? Is it a sign the spark plugs need changed or (gulp) worse? Thanks for your help! Replies to this message: spike99 (Jul 09, 2008 9:07 pm)

Replying to: antique_maggie (Jul 09, 2008 7:34 pm) Your van's engine's "chug chug" sound at idle could be from: - Water in the gas. Could even be cheap gas. - Could be plugged or clogged fuel injectors. - Could be from old / cracked spark plug wires. - Could be from too old of distributor rotor or distributor cap. - Could be from improper timing. - Could be from partial defective O2 sensor. As a suggestion, take your van to a few auto shops and ask for their repair feedback. Very hard to determine the cause without hearing the sound ourselves. Hope this helps.... .
