I mentioned there is random alarm of check signal and diagnostic tools had zero code or error messages beside mentioning fuel pump option is not recommended as I have no problem with full loading as previously mentioned.
Very good performance in. Full loads and during warming up but stalling when you back to idling only after full loading and having problem of restarting the engine immediately

If you have a rich mix then what is your fuel pressure? Did you put a gauge on it or did you just use something to open the Schrader valve on fuel rail and say yep it's there? Is the pressure 41-47 psi? Have you tried cleaning the throttle plate on both sides with choke cleaner as well as iac to prevent stalling coming to an idle? If you have a random check engine light then it's an intermittent problem

-Cleaned throttle by pass
- Examined Idle motor functioning
- the problem is not frequently taking place but it happens
- I didn't measure the fuel pressure range due to stoppage on road but released the fuel hose inserted in fuel filter and turning ignition on and the fuel is pumped well off the hose.
- it is problem of regulating mixture with load electrically.

Just what I figured on fuel measurement until you find out what the actual pressure is I have no further comments or suggestions.
