Customer Question

Hello, I have a 2002 Astro van with 4.3L and 240,000 miles. One of the valve springs and lifter was broke so I replaced it and now the van runs at a rough idle. Won't start unless you give it some gas. Will only stay running with foot on the gas whether hot or cold. Any suggestions on where to start?

Hello there! I'm Eurocar ! I will try to assist you as much as I can. Quality research = Quality answer!!
First step is to do a compression check on all cylinders but pay attention to the one you replaced the lifter and spring.
If the spring has broke there is a good possibility that either the valve adjustment is wrong or a bent valve.
Do you have a pic of the lifter that you have replaced? If so can you post it to here so I can get a view of it. Thanks
