skylinecouple Posted February 5, 2007 Share Posted February 5, 2007 Be very careful guys.I had similar problem with timing all over the place and performance would change from one minute to the next.Turned out it was the timing belt missing half it`s teeth because the dumb shit mechanic used a mitsubishi belt.

tmc_2 Posted February 6, 2007 Share Posted February 6, 2007 I had mine chaged 10tho kays ago wiht a gates racing one. ROX best take it to a mechnic could be a numbe rof things from, Fuel pressure, airflow meter, timming. I go tmy car booke din for a PFC tune and to sort out the CAS issue on the 17th so i will let u know after what the solution was for me. Apparently the cas can go bung and sometimes read 0 or 15 and all over the place. On my PFC the read out ofr timming is fine doesnt seem to move? but i dont know if the PFC actually shows wha tis really going on with timing? does any one know?

webber Posted February 6, 2007 Share Posted February 6, 2007 i have had this happen on a mates engine before, the CAS had a broken shaft onto the cam, seemed to pull out fine most of the time when i thought it was suspect and checking it, then one day pulled it out and only half came out. split where the roll ping thing joins it. i assume that at revs (got to the point it was doing it at idle) that the timing was jumping around everywhere ... simply replaced it and wammo Link to comment https://www.sau.com.au/forums/topic/154852-major-hesitation-possible-cas-probelm/#findComment-2885598 Share on other sites More sharing options...
