Here she goes!
First off... let me let you guys know.
Car before was running perfect (About 1 month ago), It has a Brand new OEM Nissan Distributor Cap, New OEM Nissan Ignition Rotor, Brand New Nissan spark plug wires, which are all about 4-6 months old, It also has NGK Standard Spark Plugs (Just about New).+
Also I got a GREAT deal on a Re-manufactured Distributor with Crank angle sensor from Autozone, made by I BELIEVE wells(company name), which I have installed about 1 month ago.
Everything is working SEAMLESSLY in my ignition system, CRISP idle, perfect driveability.
Fastforward 3 months (Which was one month ago).
I was bored and decided to take off the spark plug wires off the distributor cap ONLY, and decided to squirt a ton of Di-Electric Grease in there. The reason you may ask? ... well... I was bored.
I then took off the "power source 2 wire plug" going to the ignition coil, and decided to squirt some Di-Electric Grease in there as well, and while I was there I have "shortened" that wire, by cutting the plug off, cutting off the excess wire, and then using "crimp" connectors to re-attach it throwing away the excess wire.
I finally did all that and started the car.
BAM!
Horrible engine miss! :-(
So I took her to firehawks shop.
Ignition timing (perfect 15 degrees) (Didnt change anything to fixing the problem)
Changed spark plugs AGAIN using standard Nissan NGK's (Didnt change anything to fixing the problem)
Used a Brand spanking new Distributor cap, and cleaned the "new" wires I had (cleaned out the di-electric grease I put in there previously, which was a ton!) (Didnt change anything to fixing the problem)
So the LAST thing there were, are the spark plug wires, so I borrowed a BRAND NEW set and put them on... (Didnt change anything to fixing the problem)
Ok. So now Im stuck.
Firehawk checked the ignition coil, and it measured within spec, but we replaced it from a good running car to see if that was the problem.
(Didnt change anything to fixing the problem)
So FINALLY We took off the 2 power wires that I have cut and shortened goign to the ignition coil, and chuck connected them professionally.
Ok.
So now im lost.
Now before you guys start saying things!, listen to this:
The engine miss is ONLY at idle, and ONLY at "heavier" engine loads at LOW rpm.
But theres another thing.
The engine miss ISNT random!
It has a RYTHYM!
it goes through the EXACT SAME rythym every 2-3 minutes,
... for 20 seconds it will idle at 1k rpms but miss a bunch, and every time it "misses", the engine rpm will drop slightly, after this it goes in to a "idle at 700rpms pretty good but miss a bit", and then after this "rythym" it will go to a "idle at 4-500 rpms and want to die" rythym, and then it starts ALL over again and goes back to the first rhytym.
Cold start is PERFECT (Only in the mornings after car has sat for over 7-8 hours)
Car idles CRISPY smooth! and runs GOOD!
But this only lasts for about 4-5 minutes.
After it warms up, it goes right back to that "ryhthymic" engine miss like im describing earlier in the thread.
This does sound weird, but hey... I dont know what else to do!!!
Only when I messed with the car it started to miss... but the thing is, I have already 'reversed' my steps backwards and put on new parts and its STILL doing it!
It does not have any noticeable misses from 2500rpms and up.
Car has NO EMISSIONS, and only has the items that are required to run the car (distributor, CHTS, MAF, TPS etc...)
HELP!
