    Try cleaning the small contacts in the MAF sensor with MAF sensor cleaner do not use carb or brake cleaner. also did they use a Delco cap and rotor? I had problems with my 2000 until I replaced the cheap equipment with Delco. Good luck I hope this helps

2000 chevy astro van 4.3 v6/I changed dist.cap 4 times in 1 year rotor too/runs rough,hesitation,bad ildeing,could it be dist.gear /shaft are worn/got code po300


code p 0300 is random/ multiple misfires
each p 0300 code ( 0301,2,3,4 etc) indicates the piston at fault
this code can be from electrical , ( cap plugs wires etc ) but is mostly attributed to problem injectors and ecm injector controls --wiring and connections
check the other areas for the fault as you may be concentration on the wrong area

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


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.

I have a 1990 Chevy Astro van that stopped running on me while I was driving it. I towed it home. I replaced the fuel pump and it ran for a little while and started running very rough. So I bought another...


You say you replaced the fuel pump, what about the filter? If the filter is clogged it can cause this as can ignition. Since the car started for you after the fuel pump was changed the original problem was the fuel pump. But you should never change the pump without installing a new filter.

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure
