well im not sure bout the sensors, but theres no oil leaks engine is completly dry from top to bottom and it dont misfire.
i kept up with an insignia the other day was trying to undertake me! dont think he expected me to stay next to him and he backed off after we reached the scary side of the ton was probly the 1.8 so guess its no achievement!
ive been hearing alot about oil jet problems ive looked at the bolt on the side of the block but its not got any grooves in it, but some people say this is no way to tell if its been sorted.
i used to own a 2.0 vectra that i bought at 90,000 and sold it when i got to around 250,000 had no probs with it, just made sure was serviced and belts changed often, did start to chuck out some blue smoke before i sold it though.
finaly got round to derestricting the air box cant say i feel any difference, sounds nice under heavy acceleration! :thumbup: i need to find a cold air feed to finish it off
