I thought I had this fixed a couple times to no avail.Today I played around again after reading many posts on CpS.Last night I drove a good 15 miles with about 5 or 6 good starts then after thinking shes fixed I came to a stop sign and it stalled, started up ok next stop sign stall , the idle did surge abit after start.I started to put it in neutral at next couple of stop signs and it didnt stall.Got me home .
Today I had 5 or 6 good starts and a short run with no problems with cam sensor disconnected dont really know what this does but I read in a post to try this.
SES light is intermittant only on stall and not always .Never stays on butcode 41 is still there if I read it.
I know the cam magnet is there
I havent changed sensor yet but it is cleaned up and connections as well as harness wires are clean and have diaeltric grease.
Please help. Thanks

Well cam sensor code is gone but I have a new code 42 EST.I have taken all connections from harness apart and cleaned (dieletric grease)and taped areas.I cleaned TB , iac AND egr with TB cleaner and cleaned connections.I decided to change my computer out with a spare I had and car seemed to run great for a couple days, today its running good except for a couple stalls when stopped at lights.I am starting to think I have a issue with muffler or cat as my exhaust has a deeper drone now.Could a plugged cat cause stalling?Also checked coils and they read okay , but possibly might be module can that be tested, it is a delco.
UPDATE - I put my magnavox back on to eliminate module.
