[Gavins182]

I have been having low idle rough runing problems with my much loved 182...
Heres what ive done so far...

Changed both Lambdas for new bosch ones.. cleared codes. etc
Checked CAT
New MAP sensor
New Injectors
New TDC sensor
New Coolent sensor
New air sensor
New plugs
New ign Pack
New leads
checked and resealed manifold
New exhaust gaskets - pre lambda
Cleaned Throttle boddie

It currently sitting on my drive idleing at around 0.3-0.6 sputtering away

Im very close to setting fire to it! any help would be appriecated!

sounds fairly obvious that it's not running on all cylinders. try unplugging the injectors one at a time while its running to see if there's any difference. when you find the one that makes no difference you've found the cylinder with the problem. Check the individual components on this cylinder, injector plug, ignition lead..........

Hi, Thanks.. just checked and unpluging them one by one makes a difference on all four. When i start the car the revs sit at 1K then after about 30 seconds fall to around 0.4?

Just cleaned the throttle body to make sure there are no air leaks.. the car now starts, idles at around 1K for about 1 minute before the revs very very slowly drop until the engine cuts out? :S
Also has massive hasitation on acceleration then a sudden burst of power..............? I put my foot to the floor and nothing, then after a few seconds... full throttle?

Just been underneath and unplugged the pre cat lambda.. This appears to have stabilised the idle but im sure its not the source of the problem as both mine are brand new.. Any ideas people?

Still having issues! will not idle properly unless i unplug the lambda pre cat?? Both my lambdas are brand new...
