Falk Posted February 28, 2016 Share Posted February 28, 2016 Hello all, im gonna do my Best to explain my problems in english. When im drivning with an even throttle at 5th gear about 5500rpm the engine starts to jerking, struggle, hesitate. If I start to accelerate from that posision it goes away. I did try the same rpms at lower gears and it was No problems at all.B18c4 with cai through the front bumper and hytech headers, 200cell catalytic and a Supersprint catback.What is new the last couple of months is fuel filter, spark plugs, cables, dizzy cap and rotor, lambda sensor,vtec solenoid filter and termostat. Throttle body has been cleaned and i could not find any vacum leaks. No codes when bridging the connector. Cel light comes on but does not Flash.The idle is some what high, about 900rpm and 1500rpm before fully warm.Any sort of help or ideas is very much appreciated.

0 dr_broon Posted February 28, 2016 Share Posted February 28, 2016 I know that there's a lot of problems with lambda sensors causing jerking, but usually at lower revs... About 2-3k.Why did you change the lambda, and which brand did you use? Quote Link to comment Share on other sites More sharing options...
0 Roj Posted February 28, 2016 Share Posted February 28, 2016 Weird how it only happens in 5th gear. Have you tried resetting the ECU? Maybe it will help given that you've replaced so many parts. Quote Link to comment Share on other sites More sharing options...
