Hi, My Name is***** have over 20 years experience repairing vehicles. I am a ASE Certified Master Auto Technician. I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resoloution.I also try to give all of the information you may need expecting a positive rating. If there is any reason I cannot get a positive rating please let me know.

So am I to understand that you have a miss at lower rpms? Do you have any test equipment? Test Light, Scanner? Have you checked for codesr?

Customer: replied 2 years ago.
It's not a miss, more of a bog or lack of fuel. There are no codes displayed. I think there is slack in the throttle cable. I checked it and there's a lot of play between idle and acceleration.

do you have a fuel pressure gauge? When is the last time you changed the fuel filter?

Changed fuel filter, fuel pump, spark plug, spark plug wires when first started happening. Cleaned air filter too.

Customer: replied 2 years ago.

let me know and I can give you next steps

What do I do when I do?
Expert:  Tool Hut replied 2 years ago.

Ask them to check fuel pressure, and Vacuum. With the vacuum gauge you are looking for a nice steady needle. over 15inhg at idle and when they snap throttle a quick return to 15 or higher. any delay indicates a restriction in exhaust. Have them check for codes.
