Hi there,

My name is ***** ***** I am a licenced diagnostic technician with over 20 years experience.

I will do my best to help you with your automotive problem. Please remember, I cannot see, hear or feel your vehicle which can make diagnosing very complicated and some vehicle require extensive diagnotics that require certain diagnostics computers that can not be done over a computer or phone.Please be patient as I am not online 24 hours a day, as I do work, but I do check my page every day.A positive rating is always appreciated for my time and knowledge to help you with your problem.

Im really hoping you have the wrong firing order.. because issues like this can be very tricky to diagonos over the computer, but ill do my best to help you out.

Please let me know if you need a cylinder id diagram so that we make sure we have the right things where they should be.

If you need a diagram i will need the engine size.

If we are sure the firing order is correct than we have to start from the bottom,

Do we have spark, Fuel pressure and injector pulse.

let me know and we will go from there.

Pcmsenser not phone
Expert:  camerontech replied 1 year ago.

its possible that a sensor could be a faulty. the only way to determine that is with a scan tool and monitor a live data stream when it starts acting up. that is the only way unfortunetley or else your just throwing parts at it and wasting money.

If its spuddering at 50, it could be faulty mass airflow sensor, they can be cleaned with a qtip and brake parts cleaner if done very gently as the are extremely fragile, and see if that helps. but again,it would require a live data stream to check every sensor range performance.

let me know how things pan out, and if you need any more help

let me know!

thanks and i appreciate a positive review!
