I have a 1994 f150 4x4 5.8l. I deleted the egr and the truck threw a check engine light. I got one of those plugs that are supposed to clear the check engine for the egr. But my check engine still comes on. Check engine comes on after truck has been running for a little while and stays on until I shut the truck off. I got a obd1 scanner and I got two codes. 327 and 332. Those codes are for the egr. I’m not sure if the plug I bought doesn’t work or what is going on. Is there another way to get rid of the light?
