Corsa running problems

[Spleeble]

I have a ‘W’ reg. Corsa 1.2 Club and it was running a bit rough so I replaced the coil packs and Cat. It then ran ok for a while then the engine management warning light came on and it would hesitate under acceleration, this mainly happens when the engine is warm. In an attempt to cure the problem I replaced the Lambda, MAF and crank sensor but the problem is still there. Anyone got any ideas before I give up and drop it off at Vauxhall?

Why do people think changing parts at total random will have any chance of fixing things ?


If you had just taken it to a competent mechanic at first, chances are it would work out far cheaper than buying random parts in a vain hope it may fix something.

Buy a fault code reader and it may give you a clue but what they tell you is usually open to some interpretation. They are not too expensive and certainly cheaper than what you have already spent on not buying one.

Didn't really change parts at random, I did a bit of googling first and searched past threads on here to find common Corsa faults. Just didn't want to get bent over by a dealer. The parts were not really that expensive and they only cost me some dirty hands in labour. The coil pack needed to be changed as it now runs on 4 cylinders rather than 3.

You say that but someone somewhere must have posted up the correct problem/cause on the internet...

Fair play for looking/trying yourself I'd say...

Beats going to a dealer without a clue and reciving one up the dirt track for your trouble.

"Yes Madam, We topped up the Halogen in your lightbulbs... that'll be £400"

That why I had a crack. I didn't want to be posting "Went to dealer X for a lambda sensor and they charged me £500 as they changed my discs and pads without my permission". Seen too many posts along those lines on here.
