Pulling code 10, 40,I know that means 1cyl and 4 cyl has a problem but what I is the cause of it .
Car was running so bad bogging and surging, bucking, bad idle all the good stuff. so I found that the fuel pump was bad putting out 26 on the gage, at its best, got a new one and new fuel reg now putting out 39 . tbs is set at .99 put new cap on accel and nothing got any better. The only change it actually stalls completely now any thing I should be doing or something I missed please help I am not able to stop I am obsessed with getting it running strong and properly .
I am grateful for any help
Rob

If you are spitting codes for those cylinders from a CBT, I would check the quality of the spark for those cylinders. I use an inductive timing light and check the strobing for any burps, etc. Pull the plug and check it for gap erosion or other weirdness. A noid light can be used to check for injector pulsing electrical feed.

If you ran the CBT, did you let it test all 3 times?

Good luck.
