Jap91 Posted March 23, 2014 Share Posted March 23, 2014 Ok, To start off, Went through the NCT the other week failed on really high emissions, 3.15% on high & low idle or there abouts.. Changed the cat and lambda sensor and still the same.. Have just done the injector seals today as well but it did not bring down my high idle.. I don't know if it has fixed the emissions problem as of yet.. Will know on tuesday.. I have done a reshell on the car in late january this year and hasnt idle the same since.. Have checked all the vac lines and they all seem fine.. The car was running perfect the day we took the engine out.. Anyone got any ideas as to what it could be.. I had to turn down the idle screw after we put the engine in as it was idling at 2k or more on start up.. Even with the screw all the down it still cold starts at 1800revs.. But then settles to around 800-85o warm with all the lights on including fogs, If i turn all lights off it sits a little over 1k.. I really need this sorted as i havent drove the car in nearly a month now as a result of having no nct.. Hope someone can shed some light on this for me as its doing my head in.. Cheers lads Quote Link to post Share on other sites
Rosso321 Posted March 23, 2014 Share Posted March 23, 2014 (edited) I know it's not solving your problem but have you but in loads off wire wool and diptane for the meantime to get the nct? Have you done a diagnostic test see what comes upright be broken sensor swooping engines?Did you get a wide band test see the air to fuel ratio is perfect could be running too rich?Disconnect the battery touch the two thermals for about a minute should reset the ecu All I can think offCheck your spark plugs see is there loads off petrol on them?

rmsnoel Posted March 30, 2014 Share Posted March 30, 2014 Youve an air leak or your idle valve is broken Quote Link to post Share on other sites
gorganl2000 Posted March 31, 2014 Share Posted March 31, 2014 does your idle "hunt" when warm? usually high idle is associated with a vacuum leak. recheck all those vacuum hoses to your TB, Power Steering rack, ICV, automatic choke, etc. also, the idle screw itself carries an o-ring on it, you may want to remove it to see of its worn and leaking Quote Link to post Share on other sites
Jap91 Posted April 5, 2014 Author Share Posted April 5, 2014 Cheers for the replys lads..Found 3 small enough holes in the join of my exhaust,1 half way dwn and two at the rear joiner..
