98 Tracker 4dr 1.6L 16v 5 spd 4x4
Hello all,
Bit of vehicle history, Motor re-built 200 km ago, transmission swapped to 5 spd from 4 spd auto.
Recently replaced
Plugs (NGK Iridium factory gapped to .032, I changed to .028)
Wires (Belden)
Rotor (Napa Brand?)
Distributor cap (Napa Brand)
Egr valve
Fuel pressure regulator
Fuel Filter
Air filter
My tracker seems to have hesitation and a misfire once the rpm is around and above 2000 rpm.
Also under heavy load it seems to want to stall (off road) coming out of a deactivation.
I replaced fpr because it failed the leak down test. Would pressurize to 36psi key on, key off immediately to 0psi.
Shunt test proved it was stuck open. New one working properly.
Idle at 780-815 according to live data, ECT 81 Celsius
Also, to get my ign timing set to 5 btdc the distributor is almost maxed out of adjustment CCW. Probably close to 15-20mm away from center.
My next step was going to be confirm timing is correct (Cam/Crank/Dizzy) then injectors. Oh, I also checked the vacuum and its a stable 21 inHG
when I hit the throttle it goes to 0 then up to 25ish and settles back to 21. Not sure if that helps.
Thanks anyone whos able to help
