Hi everyone.....my first post

Having problems since Friday with my wife's Honda Jazz intermittently cutting out for a split second when accelerating and then regaining power causing the car to lurch. I am a motorcycle mechanic so have a knowledge of engines although all the sensors fitted these days make life complicated

I have had it hooked up to a analyser but it shows no faults

I have removed the EGR valve and cleaned it but it still seems to be doing it

My question is, I have unplugged the EGR valve and run the car but it still has the fault, does this eliminate the EGR valve from being the problem?

i'd say it does

Old thread! The L13 uses 8 spark plugs. I'd check each one. Sounds like it isn't firing on all 8.

Yes, probably a faulty spark plug or coil.

I know this is an old post. My wifes 2004 plate 1.4 CVT is now exhibiting the same symptoms as the OPs. It only momentarily hesitates at around 1500 - 2000 rpms under light load in "standard" CVT drive. It runs fine in 7 speed or full manual mode and will rev cleanly to the red line. Ive had the EGR off overnight for a thorough clean ( it was replaced under warranty when the car was surging but this was 12 years ago ). Both banks of spark plugs were replaced about 2 years ago. Any other possible culprits apart from these and the coil packs? Thanks.

All 8 plugs were replaced in January, but regapped to 0.8mm ( standard is 1.0-1.1mm). The car is transformed. Not sure it ran this well even when we first got it. No glitches since. YMMV.
