Hi guys,
I've been noticing how my engine would loose some power, compared from before i had it overhauled, especially in 4th gear, at higher rpms. I've also noticed a vibration through the floor and steering wheel, while decelerating from a high speed pull, from 5th to 4th to 3rd gear, as well as a big increase in fuel consumption. lastly i've noticed that on idle, (when parked) my rpms could sometimes have a sudden drop to 500rpm, but if i switch on the headlights, it will get back to normal.
(NOTE) : My mechanic says there's 3 ignition timing stages:
-Stage 1= The stock 4efte timing.
-Stage 2= The improved from stock, but piston friendly timing.
-Stage 3= The advanced timing for racing nights only.
but right now i'm set on the stock timing, which is 10 degrees i think.
What's causing this change:
- could it be an ignition issue? (it does have a very light backfire at times)
- Could it be a loss of compression problem? (having to rebuild the engine again)
- could it be a transmission issue? (slipping clutch, or loose components)
I'd really appreciate your honest feedback on this one, before i make any investments.
Thanks in advance...cheers :rockon:
