My no-cat free-flow-muffler m42 would do this occasionally. Although not nearly like that.

Sounds like a dirty idle control valve and a vacuum leak. Also try resetting the DME. It has learned all sorts of bad corrections as a result of the sensor being snipped.

Reconnect that O2 sensor man. I promise that the car will run a LOT better when you do.

Picked up one today at a local auto parts store. 100 Euros... FML Put it in still chasing idle and car running about the same havent noticed anything else. Took it for a drive through some twisty German roads through the mountains and the car is just so much fun. Its weird the car runs fantastic in the higher RPM's and just lumps around in the lowers.

Sounds like the problem is behind the steering wheel.

Also a true statement.

op is constantly running in open loop?

It's not chipped I still hit limiter at 6200. I mean yeah Im not too worried about it just thought it wasnt good to have flames shooting out of a N/A not race car engine. I love not having to run cats. made my exhaust when it was built about 90 euros cheaper. the only problem is I constantly smell like exhaust and the cops when I pull on base say my car smells like a 2 stroke dirt bike haha. Tis a true statement

[Dj Buttchug]

you need to get the o2 hooked back up. The issue here is no cat. Even a properly running car can shoot flames out the tailpipe if the exhaust is not restricted. if you are driving it somewhat hard and the exhaust is nice and hot from a pull and suddenly you let off or shift, a tiny bit of un burned fuel sails out the exhaust side. If the pipes are hot enough itll light that fuel as soon as theres enough o2 to get a burn (right at the tailpipe)

nbd. because racecar

AFM sticking maybe? It's not chipped, is it?

[duleymane///iS]

Man, you just chopped off the O2 sensor wire? You should really fix that. You get awful mileage and lose power without the O2 sensor to give the DME proper feedback about the injection system. It would probably idle a lot better, too. Is the check engine light on constantly?

Thats the thing its been like this for over a year and this just started happening. Its a Euro spec car doesnt have a check engine light.

I literally have the o2 sensor there to just plug that bung up the wires are cut and everything and have been for over a year. Also I have some like blackish soot on my bumper where the DTM tips blow all this crud up there. And when I run on full throttle and let off I usually get big puffs of grey smoke from the rear. My Mustang/Drift buddy said its unburnt fuel being blown out. Does that sound right? When I changed my plugs a month ago they looked good too :???: Not too worried about it though still going to just proceed to drive the piss out of this thing. Seat time. Best investment on driving well.

Your problem, you found it.

Think about this. The race cars that shoot flames have aggressive camshafts and lack of exhaust restriction. Your car is running rich as is with minor exhaust restriction.

No Cat, still have O2 sensor? O2 sensor giving bad info to dme may have gone into failsafe mode. Will run rich to protect motor from running too lean.
