Hello again everyone. My daughter's Volkswagen Polo has started to misfire. I had the back box replaced because it was blowing. That didn't stop the misfire but I noticed the middle section of the exhaust is also blowing.
Do you think the exhaust problem could cause a misfire?
Thanks for any advice!

Dis pack is a ht device that fires the plugs.........and has plug leads.......to the spark plugs..
Coil pack sits on the plugs and doesnt have plug leads.......
Vx's have these ........as said dunno about Volkswagons? :-/

I beg to differ, a faulty centre exhaust can cause rough running that may feel like a missfire, I experienced this some time ago on a Matra Ranho. As soon as I replaced a length of centre pip it was fine again.
Nice to hear from you again Kate :y

if it is an old car it may have a distributor rather than dis/coil pack. :-/

Yes its old - a 1996 Polo 1.4 8 valve.
Would it have a catalytic converter that could affect it?

Glad you said that Mike, as I seem to remember a u/s exhaust on one of my cars causing bad performance / misfire seemingly. ;)
I am sure that a faulty exhaust does change the pressure balance of the engine and effectivly "choke it" by back pressure and thus effect the firing of the engine. :-/ :-/
As for the Cat question Kate, if I recall correctly most cars, if not all, HAD to have cats fitted if registered after about August 1992. I know that my 1990 Senator, and those registered up to July 1992, were the last were if I wanted to I could have erradicated the cats and still passed the MOT. ;)
Your Polo therefore I am pretty sure will have a Cat fittied. :y

A very common failure on those is the coil... Really easy job but bl00dy expensive part >:( >:( >:(
Have someone with a coil tester check it for you... Most places will do that for free :y :y :y
As a word of warning... If it is the coil failing it may not give you much warning before it dies completely :o :o :o :o
Sorry to put the frighteners on there but wanted to warn you :y :y :y
Nice to see you again Kate... Keep smiling ;) ;) ;) :y :y :y

Thanks for all your help. I'm sure I'll get it sorted out now. :y
