1998 Acura RL Issues...again?

[goodguy001]

Just had it in the shop due to check engine light on. tests revealed it was an ERG Valve (?). They have installed 2 and the check engine light keeps coming back on..any ideas? there are no other error messages when they do the diagnostics.

Start by checking the vacum lines going into the EGR valve, make sure all the vacum fittings are tight.

some have a buildup in the egr passage way ! & some have a screen that gets clogged.
