Surched around for related cases but nothing helpfull.
Some history to start with, 1981 280zx 189,000 miles was sitting for 4 year's, changed all the fluids.
This is what I have done sence I got it back from the bodyshop and have started to drive it.
Changed the injectiors and injectior pluges (MSA), pallnet fuel rail, spark plug wire's (NGK), and spark plug's (NGK-R), All vacum hose's replaced.
At idle the car seem's to have a miss I can hear it and see the RPM guage ticking up and down a little, I checked the spark plug's (80 miles on them) they seem fine.
The reson I changed the spark plug's is becuase the old ones fouled out after about 20 miles.
Any idea's or pointer's?
