I am extremely Puzzled ...
I have a 1994 v6 VG30
5-speed - manual
my 1994 is extremely well taken care of
I do all my repairs / upkeep
here's the issue.
Idles perfect 800-900 rpm
One day in Nov 2017 - It started misfiring at 2500-3000 RPM - estimated
I was told it was the ICM - Ignition Control Mod - was bad
So I bought a ICM - installed it - it didnt seem to fix it - right away - so just fooling around - I took off the Coil Wire and reinstalled .. and drove it and wow no more misfiring
Drives like New again
Note: Recent – New: Plugs/wires, cap / rotor
Now we are in May 2018
About Mid-May -- it started doing the same thing - misfiring / backfire running real rough 2500-3000 rpm - no power
So I thought ICM going bad - changed out - installed new ICM - DID NOT HELP
Was told that a Coil that is going bad / getting hot will create misfire
Changed the Coil – New Coil did not fix it
So I changed the Cap/Rotor and Plugs and Plug Wires
No Help - did not fix it
Was now told that the Reluctor in the Distributor is the Problem and need to install New Distributor
Repeat Problem for you
Start up – runs prefect for 10 minutes – then engine is at normal operating temperture – then it starts to misfire / backfire at 2000+ Rpm
Let it cold down – starts runs prefect for 10 mins then repeats problem
Will a Bad Reluctor create this problem ?
