Re: 95 astro runs rough
I changed the o2 sensor,fuel filter and cleared the PCM . No differance. My next step is to check for vacc leaks and have the PCM scanned. Still rich on the exhaust, intermitten slow starts, accelerates/runs great,and idles o.k. with a soft rumble.

Re: 95 astro runs rough
I found the problem, but first....... Took the tuning valve off top of intake cover, smelled gas. Peeked inside using small mirror, saw puddle of fuel. Figured it was the finally time to replace spider unit,called around for prices: oem-$389, aftermarket $275. Going with aftermarket but decided to check over the spider unit before bying new one. So me and a friend took the intake cover off. Saw that the Fuel Pressure Regulator was leaking. Replaced it for $35 bucks! Put cover back on, runs great. Starts right up. Exhaust smells more normal. Idles evenly. That cover comes off real easy. Especially if you have two people on it. Came off in about 15 minutes. Altogether took about an hour of labor, not considering the run to the parts store and the pizza. The regulator I purchased was to my surprise the aftermarket "Help!" brand. .........now onto that clunking sound.
