Noises problem
1983 Mazda 323 4 cyl Front Wheel Drive Manual 99999 miles

when I received the car alot of vaccume hoses were missing. I had them corrected and the engine was running but had low compression in cylinders 2& 3 also cylinder 3 was not firing, (injector fault)
the engine, running on 3 cylinders had a rattle.
the ecu soon started to tick and the rpm would die off or increase. I am having trouble finding a solution to this.
the engine rattle increases as the revs do.
the ecu ticks and the revs fluctuate from idle.
