Title: MK4 GTI TURBO AGU NO SPARK ON NO.3 CYLINDER????? PLEASE HELP!!!!
Post by: bar79w on 16 December 2011, 22:09

Hi All

My engine is driving me around the twist!!!!!

My wife has a 99 'T' reg 5 door GTI 1.8 20v Turbo with the engine code of AGU. There is a misfire on it but we have checked the coilpacks, they're all working. We've put a new air mass, spark plugs and air filter on it, checked the compression, thats all fine. we've checked the injectors and swapped them around but we cant get a spark from number 3 spark plug/coil pack. Any ideas of anything else to check??????????????? If not, there will be a cheap golf mk4 up for sale soon!!!!!!!!

Any multimeter will suffice.

Also check it has a good earth.

The wiring can crack up on top of the rocker cover due to heat so give it a good once over.
