On my 2003 S10 4.3 liter (52,000miles) when I accelerate around 2 to 3 thousand rpm's I get a rattle. I can put into park and slowly run up to the
1800 rpm area and hear it. It sounds similiar to pre ign noise. Could this be the timing chain tensioner? I asked the dealer about this before it went out of warranty and he said it was probably a rattling sheet metal componet somewhere. It has been doing this all along-never any better or worse. Thanks for any help.- posted
