Hi The alternator brushes disintegrated at 105k miles, so I bought another whole alternator unit from eBay, fitted no problem checked the voltage at the battery it was above 14v. The battery was then flat the following morning so I bought another battery Bosch S4 figured the alternator cooked a cell before throwing the towel in. Since these changes the check engine light is coming on and the car idles roughly when I comes off the choke or returning to idle from revving, in fact it drops lower than normal idle speed before reluctantly returning to 750, also getting rotten egg smells from exhaust gases. Plugged in a code reader it's giving P0300, P0301,P0302,P0303 and occasionally P1090. The car is very thirsty now , 18mpg . It seems to be running ok at medium to high revs though? I've replaced no1 coil pack, no change still getting missfire fault code on that cylinder. I've cleaned the maf with electrical contact spray, to no real avail, although possible slight improvement. I've ordered another new maf, clutching at straws now any ideas? I work on the rigs so the car gets left for fortnight unused, every time I come home and go to use it something else has broken on it!
