09 Chevrolet Lacetti keeps Chugging

It wasnt me123

I have a 09 Chevrolet Lacetti and the engine keeps chugging, both when stationary and when moving. Its well serviced and maintained. Its not the plugs, ignition coil or filter. Mechanic is checking fuel pump/tank, someone suggested to me that it might be a fuel injector (whatever that is). Its fine for the first 200 metres when you start driving then the engine amber light starts flashing and car starts chugging, like its not getting power, foot is to the floor of the accelerator but no oomph.

Any suggestions would be gratefully received.

What fault code when the diagnostics were run?

I don't know that but I'll ask tomorrow

Maybe Mass Airflow (MAF) sensor damaged or needs cleaning (not with an oil based solvent) but as said find fault code & work from there.....

& It wasn't me 123.... This is what your MAF sensor housing might look like... Not say it's your problem not seeing car but symptoms similar....

Sorry for all the different post's but you could also try disconnecting MAF sensor & see if any improvement? (engine fault light may stay on but car may run better)

Thank you so much for all your comments megafan, most helpful.

I have contacted my Mechanic and told him I was trying to self diagnose and that maybe it might be the MAF sensor - he said it might - he was trying a new fuel pump first I think - I asked about the diagnostic fault code but he said he couldn't remember the number (?) but it was something like a random misfire. Dr Google tells me there is a lot of this - this must be a general code when not sure what the problem might be. Anyway, the saga goes on, luckily enough I live in town so walk most places.

Any comments gratefully received.

Good Luck It wasn't me 123.... All a bit of guessing game I'm afraid... But it might be worth your while (& anybody else viewing) buying an inexpensive OBD 2 code reader anyway even if you have no desire to work on the car your self if can give you some information to let you find out what the issue is with engine fault light without getting your hands dirty.... worth having in glovebox.... something like this or for small amount more have a look on EBAY
