Show fault Code ENG 2 001 SPN002631 01 ? - Cars & Trucks

Has an engine control module fault test been run? Do that first to see what shows up.

You need to check that fault code, you have a misfiring engine cylinder. The fault code will indicate which cylinder or cylinders is casing the misfire. Go to any Autozone and have the fault code read, tell them you have a check eng light on.

get put on diagnostics

check your starter and wiring to it

with new gen cars/trucks they show fault code in the form of a eng light on ! If the eng light is on there is a fault on diagnostics = eng management,air flow meter,feul pressure sensor,injectors etc.the trick is to find it ? workshops use a Diagnostic tool (Gen2) for Isuzu,mabe u could ask a alternative tool (launch master)also a diagnostic tool /most aftermarket workshops should be able to diagnose the problem. (this is also the reason your cruise control will not work because of the Eng Light.

tranny problem,try to reset.

Hi Regina.
You need to get the control module checked for a fault code. When an issue with the car arises, a fault will be stored in the computers memory that can be easily read by a device that simply plugs into your car. Some numbers will show and that will be the fault code. That code will tell you what he issue is. GM has a power reducer program built into the ECM (electronic control module -or brain) that when it experiences a fault it will reduce the power so people won't ignore the problem and cause worse things to happen.
Knowing GM it may be something to do with the air intake system. But thats just a guess. Get the fault code, Regina. Then you know whats wrong with your car. I'm sure going 35 mph must be a payne!!

Dear Sir,
As you said ! light is showing , it means any fault code is stored in vehicle computer memory, when ever you got time go and get eng scan and delete that fault codes, you can find that scanner any workshop you can ask for multi scanner, they will charge very minimum and problem will solve, get check before any breakdown. thanks
