FIXED: '92 MX-3 Precidia K819 hesitates on acceleration
'92 MX-3 GS Precidia K819 hesitates on acceleration. Engine feels really great until sudden loss of power kicks in while roughly accelerating.
On engine I've done so far:
*replaced ignition parts from coil to plugs
*replaced all vacuum hoses
*replaced all filters-fluids in engine
*cleaned clogged EGR tubing in IM
*replaced EM gasket
*welded exhaust tight
*taped air duct cause it's quite cracked
*adjusted TPS, ignition timing, idle
*checked for air leaks
*checked VRIS actuators
*replaced temperature sensors and cooling caps
There are no diagnostic trouble codes saved in memory. Car runs rich as far as I could say from the smell of gas that comes from exhaust and by spark plug carbonization. I have noticed oil in air duct and IM, exhaust is smoking. I haven't measured fuel pressure so far, checked lambda sensor or catalyst. I'm using online manual for trobleshooting.
Hope to get some good advice.
