hi guys, just seen a similar thread regarding an MPI seicento but my 1242 cinq turbo idles like crap and is defo running very rich.
have replaced things like lambda and vacuum hose, also tried a different dumpvalve and mapsensor but to no avail.
i read in the seicento post that there may be a leak in the exhaust system but the sei is MPI and runs two lambdas i believe?? (sorry if i'm mistaken) also i have had leaky exhaust on the TC before (turbo/manifold join as ever) but its not made it run like this.
seems to feel awfully bogged down on normal running and obv when the turbo spools up and the 2nd injector does its thing then it runs ok but it should be smooth both on and off boost.
so any ideas?
chance i may have replaced the lambda with a duff lambda etc??
any help greatly apprieciated guys
also just thought, could the CAT be blocked or knackered? have got a de-cat to put in but i'd rather just use it with CAT tbh as its bloody noisy without!
also it idles perfectly when u unclip the map wires :/ but i guess this sets everything back to nought ready to re-read when the map is plugged back in.
