Chev / GMC Misfire, poppet injector diagnosis, troubleshooting and replacement
http://www.wellsve.com/ This video demonstrates how to diagnose a sticky
poppet injector utilizing scan tool and 5 gas techniques. The upper and
lower intake are removed and replaced. The distributor cam sensor retard is
re-synced using a scan tool. The re-sync also needs to be performed at
times when a P0340 trouble code sets.

Fix It Right! - Fuel Injection System Replacement
Fix It Right! - Fuel Injection System Replacement (S1E6)
Demonstrated on a 1999 Chevrolet Blazer 4.3L V6 Vortec 2WD.
In this video, we demonstrate the process of removing the stock fuel
injection assembly, and install an upgraded assembly that converts the
vehicle to full multiport fuel injection. This is a fairly straightforward
repair to resolve a common issue with the older CFI and "upgraded" CSFI
systems used on GM's Vortec engines: sticking poppet valves that dump raw
The stock fuel injection system for 4.3L V6 and 5.7L V8 GM Vortec engines
consists of a central injector housing containing either a sequencer (for
the older CFI design) or six injector solenoids (for the newer CSFI
redesign) and six tubes with a poppet valve on each tube end, each of which
are inserted into the intake manifold. The poppet valves are subject to
clogging from microscopic debris in the fuel, varnish buildup, etc. Once
one or more of them clog, the engine starts to run rough and mileage starts
to nosedive. Since the engine control computer will detect a rich condition
due to excess fuel consumption and will begin leaning out the engine to
compensate, watch for long fuel trims moving strongly negative if checking
the vehicle with a scanner capable of reading OBD-II datastreams.
The replacement fuel injection assembly is a new design, and instead of
using poppet valves and a single injector and sequencer manifold or central
bank of injectors, the new assembly replaces each poppet valve with a
miniature injector on each tube end. This design has a number of
advantages: improved throttle response since there's no transit time for
pressurized fuel to travel down the individual injector lines, improved
fuel economy (not the least of which is from not constantly dripping fuel),
increased horsepower due to improved
fuel delivery efficiency, and increased reliability since the injectors
have a more forceful open/close action. Generally speaking, customers that
have had this procedure performed had positive opinions on their vehicle's

About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give
do-it-yourselfers basic instructions on proper vehicle repair and
maintenance. All of our videos show real repairs being performed on real
vehicles by real technicians in a real auto shop. (Repairs are filmed and
shown with the permission of the vehicles' owners.) Although there may be
more than one way to perform any particular repair (and in many cases there
are lots of ways!) we try to focus on the methods that will be safest and
most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex
or dangerous for DIY, or require specialized tooling, expertise, equipment,
and/or certifications. Those episodes will highlight the importance of
hiring a professional auto technician for tasks that are not DIY-friendly,
and demonstrate why such tasks are best left to professionals.

94 s10 blazer missfire and CPI spider injector repair
truck started running very bad like the injectors were leaking so i popped
the plenum off and found that whoever had it before me fixed the gas lines
with rubber line and zip ties and wrapped the small ones in electrical
tape. so i went ahead and took my new set of injectors from my totaled
blazer and still running bad. so i thought well just replace the coil that
i also had a spare. and what ya know it runs better than ever.
