Well after owning my car for a little over a year it developed a leaky head gasket. I decided it was time to reseal the motor and try to make it run like as good as new, ever since the day I bought the car it has stumbled under 3000 rmp and hesitates throughout the rpm range. I know these motors have there weaknesses and are not very powerful so im not expecting a lot just something more drivable.
My car is a 94 loyale wagon 5 speed push button 4wd and ea82 spfi it has 170,000kms (100,000miles) The recent parts i have put into my car where, Head gasket, rear main, clutch, valve stem seals, cam seals, valve cover seals, intake manifold gasket, throttle body rebuild, thermostat, coolant temp sensor, pcv valve, air filter, fuel filter, cap, rotor, plug wires and spark plugs.
The timing was set and the motor was put back in the car, everything plugged in and filled up with fluids. I gutted the cat before reinstalling with new exhaust gaskets and was ready to do my first test run. After the car was warm and all the fluids levelled off it seemed it be running the same as before just with out the mess, so fired it up again to set the distributor timing it was a little bit retarded but nothing crazy so set it to 20btdc. The car ran the same maybe a little smother idle but nothing fantastic, Being a little confused now on where the problem was coming from we decided to test my maf sensor and the tps both checked in with factory specs now im not sure where to go I don't really think my fuel system is the issu if any thing my motor seems to be running rich.
Im at the point where im about to take it to a professional mechanic, I didn't really want to create a new post when there is so much info out there already but im getting close to the end of my technical now how and i need some guidance. Is there anything ive missed? should i be looking deeper into my fuel system? or should i just take it to a mechanic to see what they have to say?
Any input will be much appreciated hopefully someone will be able to spot something ive missed
