Hi there

I am having a nightmare with my vauxhall astra 99 8v I have just had a new thermostat put in because I had mayo round engine and thermostat stopped working.I had cam belt changed at the same time because of the location of the thermostat(silly place to put it!) but I have now got a flat spot on acceleration and she quite jerky when doing 60 - 70 and really doesn't like low revs! It likes to be driven hard or thrashed but I don't like to do this. What could be wrong with it now? Still no engine management light thoe. I hate vauxhalls! Its had new breather pipes ,spark plugs. Fuel filter, air filter, and engine and fuel flush,full service (mayo gone) emissions past.. can some one help before I burn it lol!

Look forward to hearing from some one

Replace the Ignition Control Module (ICM) and coil. I recommend replacing them every 192,000 kilometers or 10 years, whichever comes first.

Hi thanks for getting back.. the coil pack had been mentioned by a friend so you have comfirmed this needs to be done the car is 10 years old with 58.000 miles on clock so what you have stated could possibly solve our problem thanks Texas greasemonkey.. ill let you no how I get on xx
