intermittent problem - ZR-1 Net Registry Forums

wikdzr1 · 09-16-2005

I am currently experiencing an intermittent problem which is driving me nuts, every few days al of a sudden my ZR1 will miss very badly while driving, when I pull over and restart it will again run very strong until the next episode occurs. I have replaced fuel pumps, Prom, plugs, Map, IAC , Battery, disabled the VAT, any suggestions would be helpful. Could it be plug wires or coil pack that is my next area to explore? Any suggestions on which plug wires & coils to purchase? (The car has 70k miles with original wires, coils & injectors) I have pulled the codes by jumping pin A to G under the dash and it came up 1) H41 (4) H46,H54 (9) H72. I have been throwing cash at this problem for over 1yr shot gun approach. I realy appreciate the help
