  still failing smog..HELP please« » Reply  Edit


k i have done everything. full tune up(fuel filter/air filter/spark plugs/wires/cap/rotor), new O2 sensor, new caty, new timing belt/water pump/head gasket/arp headstuds(solved heating prob. resurfaced head), fairly new b16 injectors.

now the problem is this. we tested it with a tail pipe test. at idle it was okay and rpms dont jump around at idle..idle is smooth(HC level of 68) and then he ran it at 2500rpms and it was okay {at like 120 hc level}(from 1500-4000rpms it cant hold a steady rpm without dropping and raising) so then he let the rpms back to idle and then suddenly the HC levels went to 800, they are supposed to be under 100 at idle. now im guessin whatever is causing the car not to hold a consitent speed is casuing the smog issue. Question is have any of you ran into this problem..when i drive under 4k it has a little jerk cuz it cant hold a steady spead. what can cause this problem?

Fuel Filter/pump may be causing the jerking..

If you get that rectified and still can't pass try some stuff called "Guaranteed To Pass" you can buy it at autozone/checker, any parts store really, should do the trick.

test your map sensor.Or check your cold start valve,that can start surging on your car.Or pm "THESMOGMAN"

but can it cause the car to run rich? its running high HC levels out the tail pipe..so whatever is causing the inconsistent speads is related to the high HC leves? and the cold start valve surges your rpms at idle..my idle is fine.

About .5 to 4.7 Volts. Maybe you have a vacuum leak causing the unsteady revs.

ya im starting to think that and i think i might know where it is..cuz i broke a check valve and had to replace it under the IM. it goes to a box that bolted to the back of the block..i might have torn that hose before when i was tryin to replace the check valve. thats the only thing i can think of right now..there are like 4 other people with this prob on honda tech.
