PathinTX Posted May 31, 2018 Share Posted May 31, 2018 (edited) Hello All I am extremely Puzzled ... I have a 1994 v6 VG30 5-speed - manual 262,000 miles my 1994 is extremely well taken care of I do all my repairs / upkeep here's the issue. Nov 2017 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 ?
