hi all am new to the forum and wondered if anyone could help
i have recently bought a my01 bugeye and a few days after getting it i could feel a slight misfire especially when pushing it in 3rd gear, then every so often the misfire gets worse and th engine light flashes then says on,
the car also feels quite flat even when you cant feel the misfire
i have taken it back to were i bought it and they said it was the coil packs and replaced them
2 days later the car was the same again
then they said it was the airflow meter and replaced that
2 days later the car is the same again,but now they are saying its not covered for this under the warrenty and they only didi it out of good faith
i have had it checked by someone else and am told they have changed the parts they say
any ideas on what to try next seeing as it looks like ill have to sort it myself now
beggining to wish id kept my revo'd golf

 

Try the plugs as a cheap first thing to try,Is it showing any fault codes.Often a misfire code is shown and its the neutral position sensor thats at fault.

I would be wanting to know why its not covered by the warranty?
And if you/ve had it a very short time and it was from a dealer I'd take it back tell them its faulty and not fit for the purpose it was sold for and ask for a refund,They'll probably want to fix it instead of refunding your money.

v5man on here had this problem with his and changed almost everything and couldnt cure the problem and it turned out to be a headgasget failure which is why i would insist the garage sorted it.

 

not showing any codes just comes up with misfire on 2,3 and 4
i have read the warranty and it covers hardly anything really its not worth having
it has just been serviced but they did this and before that it was all main dealer serviced

 

When my sport was misfiring, it wouldn't idle, cut out when driving and a whole list of other problems. In the end it cost me £1300, turned out to be the Cobra immobilizer, and I only found that out cos I had it removed so I could on a clean wiring loom to fault find.

 

Surely when you bought it, it was serviced by the dealer before selling it to you, which I would assume includes the plugs, oil, air filter etc, check your paperwork, if not, the first place I would look at would be the plugs.
Also was the car standing around for a long time on the forecourt ?????
Maybe it needs a long run just to clear it out (unless you done that already!)

Kev.

 

yeah the dealer serviced it plugs etc or so they said and stamped the book
but i suppose new plugs could be faulty so ill change them tho not an easy job
it idles fine and never cuts out

 

i have exactly the same problem at the moment and its going to cheam motors next week to get looked at and serviced

 

Check your plug gaps...If they havnt been set properly when they were put in, then it has been known for the sparks to be "blown out" whilst on boost...

good luck

 

I'd check the plug gaps as J-K suggested. Try them at .7mm, check what grade they are and the boost you are running. Where are you based?

 

am based in preston, lancs m8
gonna get a m8 to look at it this week who does all the major work on my astra rally car (dont even get me started on this thing its in a far worse state)
was talking to him before and he seems to think it may be plugs as well heres hoping
thanks for all the responses definatley the most friendly forum ive ever been on

 

I had this after a service.

After ages and three goes at fixing it, the dealer admitted it was one of the plug leads at fault.
They replaced it, and it was sorted.

Look for simple things first, plugs, leads etc, esp if they have been disturbed in a service.

Ive just cured a misfire in my car which started back in april! Diagnostic didnt show anything and no lights were on.

First i changed the plugs - still doing it.

Then MAF - was fine for a week.

The garage gave me some old leads which they said were fine - still doing it.

I bought some new leads the other week - car fine.

Only cost £330 to fix!

 

it wouldnt surprise me if it was the leads actually as its a very iratic misfire
sometimes worse than others
was out in it this morn and its usually fine on idle but it was being very lumpy today

 

changed the plugs and it seems to have got rid of the bad misfire and the engine light has stopped coming on
but it still hesitates and feels kind of like its missing when push it especially
in 3rd between 4k and 6k revs

 

Clean your boost solenoid out with some brake cleaner. Have you gpt a boost gauge?

 

i havent m8 no
the car is standard apart from rear spoiler

 

Yes.
