I just replaced all of the fuel lines except above fuel tank and all 4 fuel injectors. Injectors all have new hoses and connectors. Now when I start the engine wether the engine is cold or hot it stumbles for the first minute or so. Just like it is staving for more fuel. If I accelerate the engine for a minute it runs great and will idle nice. I checked the TPS for a clicking sound just off idle and also wide open all with engine off. No sound. My hearing isn't the best!
I do have a hum on the idle control valve with the ignition on. The fuel injectors don't seem to be seated really tight. Does the metal bracket that holds the injectors in place needs to be bent or readjusted so the injectors are held super tight to the engine? Does this affect the start up problem? I also noticed that the fuel pump seems to be making a new noise. Could this affect the problem? I didn't have this problem before.
Any information or help would be great.
