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.

Ok, thanks for replying

Thanks, is that something to care about if it is broken?

I would be glad if a friendly soul could identify this ting that is attached to the intake manifold.

But did you feel any gain of power somewhere in the register? Do you have stock extractors?

This is my first post and i hope it is in the correct section, i am also swedish so i hope you all can understand my english. The car is a Civic mb6 b18c4 imported from italy. I am trying to decide if i should fit a 60mm SRS or a 50mm Supersprint mid pipe to my setup. The current setup is a hytech header connected to a srs 200cell catalytic converter, stock midpipe and a big backbox muffler which will be replaced later. A cai will also replace my sri when i order the mid section exhaust. https://www.akr-performance.com/p/srs-mid-pipe-b-pipe-stainless-steel-mids-cv92 and http://www.supersprint.com/ww-en/honda-civic-96--01-ek-ma-mb-mc/honda-civic-mb6-97-00-5p-18-vti-169-hp/centre-exhaust---50-v1.aspx#!/ There will be no future tuning, like port polish, cams etc Cheers/ Jens Falk, Sweden
