cqtama Posted October 23, 2009 Report Share Posted October 23, 2009 i drive an '01 chevey balzer 4.3l 6 cyl. ok so i was driving to work the other day and my check engine light came on so i broke out the trusty snapon code reader and it said i had a random multiple misfire... ok so i changed the spark plugs, still did it, got new wires, didnt help and finally did the cap and still nada. im stumped i cant figure out why it still has a misfire. i cleared all the codes drove around for a little bit and it came back. so i read it again and it still came up with the same problem. any ideas?

HaMSaMMiCH Posted October 23, 2009 Report Share Posted October 23, 2009 my 97 silverado has been doing the same thing sense i swaped out the 105amp small case for the 140amp large case from a tahoe. my ecu burned up the same week and i got a new one from a junk yard, so i dont know if its the ecu or the alt, but if you figure it out, let me know.

kandiman71874 Posted October 23, 2009 Report Share Posted October 23, 2009 Being you have an actual scanner, did you go into the misfire counters and see which actual cylinder is missing to start with? you may have a leaking pressure regulator on the injection spider set up thats causing the miss Quote Daily Driver 1999 Kia Sephia Kenwood DNX-893s Audison Bit One Processor 2 Dat 4.125's Sundown Audio SCV-6k Hertz hsk-165xl's Mids running active Focal V30 Series Tweeters running active Sundown Sa-8 v1's in the doors 2 Sundown Zv5 12's Lots of Hushmat Big 3+ and 3 + & 3- runs of Trystar 2/0 2 Dc Power Engineering 320 HP Alts 2017 Comp Vehicle 2006 Toyota 4 Runner Kenwood Excelon DNX-893s Audison Bit One HD DSP 4 Sundown Sa 6.5v2 Component Sets Focal Access 6.5 2 ways Sundown Audio Sax-50.4 Sundown Audio Sax-100.4 2 Dc Power 370xp Northstar agm27f Northstar agm65 2 Northstar asmagm 480's 2 Dual 1 Sundown Nightshade v3 12's 2 Sundown SCV-7500's All SMD Fuse Holders Shitload Of Sundown 1/0 120 sq ft Second Skin Damp Pro No, Its Not A Burp Truck!!!! 2016 Season 3rd place in Xtreme 1 At Finals 2016 Season 6th Place In Kaos 1 At Finals ( Blew The Subs Up In First Round Eliminations) 2 Kansas State Records Set In 2016 In Xtreme 1 And Kaos 1 In Midwest SPL David said: audio is a lifestyle, not a hobby newls1 I cant read a tape to save my life... 1/2's are ok, but other marks confuse me kingsuv only men who cant read a tape, take it in the ass kingsuv you sir, get a pink hard hat on jobsites Link to comment Share on other sites More sharing options...

dustin_shull Posted October 24, 2009 Report Share Posted October 24, 2009 well, the 96-00 vortecs are famous for multiple problems, such as egr valve, spider injector and assembly, fuel pressure regulator, etc..... however, it could be something minor, like a bad knock sensor playing with the timing or could be low fuel pressure from the pump....many things could cause this....

maniac74 Posted November 17, 2009 Report Share Posted November 17, 2009 (edited) could be a bad module in the distributer or a leaking intake manifold gasket the vortec's are known for that aswell just did mine on my suburban. are you losing any coolant?

Kranny Posted November 17, 2009 Report Share Posted November 17, 2009 not a big help but our schools wood shop teachers silverado had multiple misfirings (every stroke) and a fuel injector cleaner worked wonders. the truck didnt sound like a diesel anymore.
