Flat spot on acceleration

Postby apgandy » Sat Jan 12, 2019 6:54 pm

Hi, now I have a 1.6cc and the thing runs and starts fine but once into second gear and beyond it is very flat power wise until you reach 3k rpm and above? Ticks over at 850rpm no problem starting but just feels like there is no torque unless you rev its nuts off. Lots of torque in first but then goes flat until you reach much high rpm. Thinking maybe a tps reset as I don't think its the coil packs but maybe someone could help with this. Tia.

I would first check the air filter element, the inlet air pressure/temp sensor and the crankshaft position sensor for cleanliness.

Based on my recent experience I would check the plugs as well.

Hi,
I would check the plugs and perform a compression test while you are there. Air filter unlikely, but no harm checking.
Assuming its not mechanical then I would if possible on this model; reset the ECU so the TPS and some aspects of timing and fueling are re-learnt.
A bottle of injector cleaner on a low tank of fuel followed by a 70MPH burn on the motorway can only harm your pocket.
Cheers,
Iain.

Thanks spitfire6 but have checked the usual things and no not mechanical just abit lethargic in second if you lose revs! Like I said been too use to turbo diesel power delivery as it goes pretty dam well but it dose it higher into the rev band.

Took me a while to relearn the joys of high revving 16v engines. My previous cars have for the last 10 yrs have all been 2.2L turbo diesels and 2L petrol turbos.

Quite like the fact I can drive the 206 at a sensible pace and it just chugs along but can get a bit more fun once over 4000 revs. :)

Drives much better with the new plugs though.

Yes its a nippy little car and with a small tweak here and there handle quite well for todays roads. Wouldn't want to use one for motorway work though but then there isn't any in the highlands.
