Rough idle 95 astro van, I did a full tune up , plugs,wires,cap, rotor,air filter,and fuel filter and cleaned egr vavle.

My 95 astro van has a rough idle and I have done a full tune up. Plugs,wires,cap,rotor,air and fuel filter,pcv valve and cleaned the egr valve. Some times it idles fine and some times rough. I noticed that it idles better cold than hot. And if i park it and let it sit for a few minutes with it turned off it will idle ok till i drive it and get to a stop light and then it idles rough.

I actually had to replace my EGR valve and the gasket. I clean the valve well and reused both. I don't think the gasket sealed well enough though. So I went ahead and got a new valve, gasket and changed them. It runs a lot smoother now.

Perform a valve clearance inspection and adjust if necessary. Tight or sticking valves will cause a misfire or rough running concern. Note: Perform valve adjustment when the engine is stone cold. 4cyl: INT 0.26mm EXH: 0.30mm (V6 engine are hydraulic and no adjust necessary.) Also check for a sticking or stuck open EGR valve. For diagnostic purposes only: Remove the EGR valve. Place a business card over the EGR passage and bolt the EGR valve back on. This plugs the EGR ports and if the misfire goes away the EGR valve is partially stuck open and is defective.
Check for low fuel pressure. Check for low compression. Check cam timing. Check for a weak ignition coil. Also don't over look the possibility of worn or broken engine mounts which cause excessive engine movement and engine vibration. -hope this helps

Astro Van is running rough


No,the oil ratings 10w30 and so refer to how the oil viscosity reacts to hot and cold.As far as running rough,when was the last time is was tuned up,cap and rotor if applicable,spark plugs and air filter?Is it carburated or EFI?

2000 astro van running bad


Try cleaning the trotle body at the butterfly,they tend to carbon up and not let proper air mixture at idle,tailtail sign some times is feels like the throtle pedal sticks or pops when depressing it.
