I've been experiencing a problem once in a while and would really appreciate any thoughts;
Whilst the car is no probs in normal conditions, Occasionaly when doing a kickdown, the revs drop to 2000 and then wont go above - the car still drives but keeps a consistent max speed and 2k revs even if I hold my foot to the floor, usually about 30 mph.
If I keep driving in this go-slow mode, it can sometimes clear up after 10 seconds or so, but other times wont go away.
no warning lights or faults show on db.
When I pull over, the engine idles around 1k, but can dip a bit below and bobble about threatening to fade out but never does, or has once. If I rev it the revs get stuck at around 2000, maybe a little above, but wont go over however hard the accelerator is pushed.
If I do a quick turn off & restart the engine, it idles, revs & drives fine.
I've noticed it is more frequent if I kickdown very soon after starting the engine from cold - and it is less likely to happen after ive been driving for a while, but having said that it can happen any time, & could be my imagination.
Something else I have noticed but not sure if connected - occasional the engine is sluggish through 2-3000revs then has no probs shooting up beyond 3000. The way it fights through to break free above 3000 revs and then lets loose gives the feeling of feels like a blockage in a pipe offering resistance then clearing (not that it is that..just the sensation it gives)
I should probably add that im actually a fairly slow & considerate driver, its not like i do the kickdowns that often, but when you know theres a prob, it makes me want to test it...also today pulling onto the motorway got stuck at 60mph,
Obviously quite concerned it could be a pricey gearbox job, would make my day if it could all be put down to a faulty MAF, fingers very crossed, any thoughs? many thanks
