Hesitating while driving

[tom325sport]

My 325i cab has this annoying hesitation while driving. It starts and idles lovely and even on slow acceleration it seems fine. It's when I put my foot down it bogs down then comes to life.

I've cleaned and set the TPS, changed the fuel filter, cleaned the dizzy/rotor, new air filter and air flow meter.

Any help much appreciated. Maybe the exhaust? It's a scorpion - yes I need to change this!

when were the injectors last overhauled?

I was hoping it wasn't them. Anyway you can tell/rule them out?

not really, if they have not be done in years I would argue its worth doing them to simply rule them out.

They are fiddly but easy enough to remove. I would then send them to injectortine and have them overhauled and balanced..refitting is also a 20 minute job.

It may even pay you to buy a used set have them cleaned and then fit the overhauled ones to save down time.

OK good advise - will look into doing that.

Do you think there is anything else that could be causing the problem?
I've read the blue temp sensor? But not sure how that would make the car hesitant?

Possible, but the injectors sound like the prime suspects.
