hello to all,,I am the proud owner of a 2002 Cavalier LS sport coupe 5 speed with the 2.2 ecotec that i bought new in 2001,never had a problem with it. has about 70 k on it,now one thing has me bothered about the plugs i put in a year ago Bosch Platinum+4 Spark Plug i think they were the Iridium models anyway i read some where that these plugs may burn out some module???? has anyone had a problem useing these plugs????

also has anyone changed the fluid in the manual transaxle??? owners manual says you dont have to change it unless its leaking???hayes manual says it should be changed at 50 k


thanks to all

 

i wouldnt run anything more then a platinum plus 2 and single platinums put out just as much spark.
