crispy_chick3n Posted April 27, 2014 Report Share Posted April 27, 2014 Hell with mfi, carb it! I can get 4150 manifolds for that engine. only issue with a carb on it would be getting the CEL off, and getting things reading correctly for emissions. with the mfi system there is support from chevrolet so people who need to can still pass emissions. yes you would be able to pass emissions with a carb, but it would require more work to be done This page is crispy_chick3n approved. © crispy_chick3n inc Link to comment Share on other sites More sharing options...
sphinxbccp Posted April 27, 2014 Report Share Posted April 27, 2014 My blazer had most of the same problems, a can of MAF sensor cleaner and about half an hour of cleaning it and i was good, all codes cleared themselves and to this day i haven't had another code. It didn't look dirty either, but a 10 dollar can of cleaner its better then replacing all my O2 sensors like the "professional" was telling me Build log: Click Feedback: http://www.stevemead...xbccp-feedback/ 03 Chevy Blazer - IPad Air 2 - ALPINE Head Unit - 4 DC XL 18s - 2 DC 3.5k - ALPINE TYPE R 5.25 COMP - 3 ALPINE TYPE R 6.5 COMPs - DC 175.4 - DC HO Alt - D3400 - 4 XP3000s - KNU 0ga - 60 SqFt Damp Pro Lots more...

Tarball Posted April 27, 2014 Report Share Posted April 27, 2014 Just seeing this thread for the first time. I assume you are have the CSEFI engine and not the MFI. As mentioned the CSEFI uses the spider injectors. What plugs did you use on the tune up - I recommend only AC Delco platinum on the vortec engines If you sprayed any type of cleaner into the intake while the vehicle was running - TB / Carb / MAF / EGR cleaners - then chances are your CAT is clogged and needs to be replaced - with 80x thousand miles on the Cat its a good bet its bad anyways on a vortec. Find a place that sells gas without ethanol and don't go anywhere else for gas. You probably need to replace all your 02 sensors and the Cat and maybe even the muffler - I have had the cat go bad in these and shit itself into the muffler - cat was empty when removed and all the guts were clogging the muffler. Have you done a compression check yet?

boom50cal Posted April 28, 2014 Report Share Posted April 28, 2014 Emmisions? What tree huggin, Obama humpin, tofu fuckin state does he live in? On the real, I always forget about emissions. I've never had them where I've lived. Utah, Fuck emissions. OKLAHOMA! Correct me if I'm wrong but wouldn't he have to run a standalone tranny controller too? Or could he use the factory PCM? Off topic.. Clogged cats, fucked up pressure regulator, and failing spider injectors. http://www.fuelinjector.citymaker.com/Vortec_spider_fuel_injection_conversion.html Wild shot in the dark, but it could be a failing cam position sensor also, to some extent. I goofed on mine in my car and it was causing a wicked extended crank on start. On 1/4/2013 at 9:31 PM, HatersGonnaHate said: Wow. 184 posts and I think you're a fucking asshole.

Off topic.. tranny should be fine as long as he doesnt mess with the cylinder ignition system. you remove the tach signal from the pcm and shit gets fucked up in a hurry.

Jessica Posted May 2, 2014 Report Share Posted May 2, 2014 My dad told my a lot of those 4.3 had soft cams. But he also said that smell you had was usually a bad cat. But the cat may be bad because the came is worn out causing shity exhaust and trashing the cats. Just food for thought, Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.
