Hi you all. Greets from snowy finland!
My wife's car have following problem: While accelerating any gear punto starts to sputter from ca. 3500rpm up. When I change gear example from 3 to 4 it stops from sputtering and runs fine until engine hits to "magical" rounds and sputters again. Engine runs fine when idle and lower rpm's than 3500 (estimated).
What I've done so far. I changed oil and filter when I bought this car (readout was about 84000 km, now 87000 km). Last week I changed ignition coils, spark plugs, air filter and gas filter. Didn't help much so it sounds like lambda problem, right? BUT injection light appears only when I start the engine and doesn't appear when driving car. Could this still be lambda problem. I've already bought new lambda but I don't want to waste another 65 euros for nothing (coils costs that :-/). Hope you can give me some help.
Cheers!
