I have a hyudai eon 814cc 3 cylinder mpfi. I have fitted my car with cng sequential kit. The day it was fitted the car started stalling while driving. The mechanic adjusted the ecu and advancer of cng kit and then it ran fine for some time. The car was even scanned twice at that time but didn't show any codes. Then the advance timing was set and car ran fine. But it randomly stalled someday and then the frquency of stalling increased slowly. By resetting the advncer and ecu the problem goes away for sometime but comes again. I had to drive it with very little acceleration to prevent stalling. The mechanic changed the whole cng ecu and wiring kit but the problem is still there. Sometimes the fuel change over switch doesn't work and when it works car stalls or jerks. Checked spark plugs nothing wrong. Car runs fine but random stalling occurs with increased frequency and no error code is generated. Please help as it's been four months and the mechanics can't understand the problem with it. Help will be deeply appreciated.
have the same problem?
