My car work perfecly at low trotthle, but when i put the feet on the pedal a little harder it have a total loss of powerlike like if you the ignition for 1 second. What could be? i was thinking the fuel pump. The car have benn stopped for 2 month was working perfect before. Do you think could be the ignition problem? how to do a throuble shooting??
Thanks and Regards

If you can never boost the car the ecu could be in limp mode. Not sure if thats possible with a knightsports ecu, but thats what it sounds like.

 

What mean in limp mode?
Thanks for reply

Once it happened to me too and i noticed that i was running on low fuel. From that time onwards i always made sure i had at least 1/4 tank full. (It never happened again.)

I don't know if that helped....just my experience....

 

OK thanks after a troubleshooting i had notice that should be the fuel pump sice work at low pressure, i will replace and see if i solve the problem.
Have a fun

 

when you put your foot down, does it sound like its miss firing?

 

I dont know, onstly the meccanic is working on the car, i just follow and give him direction

 

Since the car have been unused foe 2 month, could be the low voltage due to battery discharge?
Anyway as enought power to start smooth the engine without problem.
Thanks
