Or are you saying you re-installed the Bosch plugs?

Re: Correct injectors?
Jaap, that's good news. My opinion is that you should drive it awhile and then pull the plugs again especially on the 2,4,6,8 cylinders. (Funny how that's the right engine side.) You mentioned that those plugs 2,4,6 showed deteriorated electrodes and in an earlier post you said "When i bought the Z there was a constant white fog behind the car, that`s now gone". Sometimes a white fog is an indication of a coolant leak which you may have fixed. So it may be wise to inspect the plugs after awhile to see if all is well.

http://www.gnttype.org/techarea/engine/plugs.html Upon the recommendation of Pete's (a well respected ZR-1 mechanic and racer) I installed the AC Delco 41 602 and have been using that plug for over 6 years with NO problems at all. (And, they cost much less than some more exotic plugs do - less than 1/2 a tank of gasoline; cost is low enough they can be replaced often to keep them always like new. Also, compression checks should be done with the battery fully charged, and a battery charger connected to keep the battery at full charge between each cylinder test. Otherwise, what might look like low compression on some cylinders might be because the battery is becoming discharged. I run my compression checks by taking my reading after equal number of compression strokes (5 to 7 compression strokes is usually enough to reach the peak, I find). And, I wait until the charging current from the charger drops down to 3 Amperes or less (fully charged) before testing again. That way I feel if I get a low reading it is NOT due to the battery being discharged. Glad to hear it is running well. I'd want to keep an eye on those plugs for a while, to be sure there is nothing wrong with them.

Re: Correct injectors?
What about if the Catalytic converter is blocked/ damaged on the even bank....., and on the uneven bank not. Abnormal things are going to happen than. Like unstable engine load, more heat, which can damage the engine. He needs to look at his exhaust manifolds.

We've had the opposite experience happen here. Some installed exotic Bosch plugs and developed a miss. Not only on LT-5 but also BMW. AL-ZR1 can tell you about his experience w them. Installed stock plugs and bingo. I run NGK6E plugs on my LT-5 and never think twice about them,
