people wont agree with me but i had a VY SV8 cammed manual and got it tuned on e10 unleaded, pullled the mainfold to do a upgrade and intakeports were pretty clean that 10% helps to me. Car ran great and didnt need high octane as cam bleeds comp and was std compression.
I cant see the sprays being a complete clean but i had something on cyl 3 jamming a valve open(tested all other possible issues, compression test showed low comp) a fraction hence misfire rough idle check engine etc. After 1 1/2 400g cans at 3000rpm and some back crap on my driveway car is...
daily shes does a 60km trip to work 60k home so gets a good run. Held it in 4th at 110 for a bit to clear any crap in cats. No engine light no miss fires
Dropped misses of at airport this morning all good on way home check engine misfire on cyl3, did the normal change plugs coil tricks misfire on 3cyl still there. 2 cans of intake clean and seems to be ok atm, black crap out the exhausts
sidi motor??
Parents have a early series 2 with sidi engine currently at 99000 full holden service history(every 15k) and it chews through coils and plugs evrey couple of years. Plus 2 02 sensors.
just did my first ls1 starter motor(vz SS), ffs you have to take the right exhaust manifold off to do it. While i was there put new headers on plugs leads etc plus 2 broken header bolts another GM issue
bought car from a auction as a work hack had 210000 and had missfire then on cyl 2, used some carbon cleaner stuff through the throttle while lad held the revs up(terrible smoke smell) fixed the misfire but at 222000 its cylinder 3 now. Not spending much on it now timing chain noise at start up...
