So then what code do you get ???
What do you mean by Delta Pressure switch ???
Pressurized fuel system cleaning is a service. You don't want to buy the machine.
Things to try:
Check plug gap.
Reset PCM.
Clean the MAF.
Check for vacuum leaks. Check the PCV valve and hoses carefully.
Make sure the secondaries work properly, or just unhook them and tie them closed for test purposes.
Unhook and plug the vacuum hose to the EGR valve for test purposes.
Test the TPS with a meter or get a new one.
Put a fuel pressure guage on it where you can see it while you drive around.
