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.

GM 4.3L V6 / 5.7L V8 - Fuel Spider Swap, SCPI to MPFI
Video of me swapping the fuel spider out of my 1999 vortec 4.3l after it
All the tools and tricks needed for the job are outlined in the video.
5/8'' Crows foot will be your best friend.
here were the symptoms:
Truck would start rough and require throttle to even out when warm. Would
usually cold start fine. This lasted for about 6 months, then it got to
where it would be so flooded it would run like shit and not even out. fuel
pressure regulator was dumping fuel out of itself and into the upper
intake; whenever the fuel pump turned off. I demonstrated this in the video
with the plenum off and the injectors plugged in.

If your have a pre-2003 4.3L I highly recommend you replace your poppets
with the new multi port spider. Just about the best upgrade you could do.
Changed the plugs and wires as well and now get 19mpg (up from 16 with the

4.3L/5.7L Vortec V6/V8 | Throttle Body Blade Mod | 262/350ci
Easy free way to gain a noticeably better throttle response. Does not gain
companies claim. Please read description. Thanks.
The mod is to remove the diffuser / restrictor off the bottom of the blade
to increase airflow into the engine. free alternative to a $40 cfm tech
Make sure you reset the computer (reset by disconnecting battery)
Took me about an hour from start to finish
please don't tell me that my front 2 cylinders will lean out. there is no
need to restrict the EGR due to this mod....

GM Troubleshooting Part 5 - Fuel System including filter, pump, injector, regulator
This is part 5 of a multi part video series about how to troubleshoot any
ignition, fuel injection or timing issue. I describe the fuel system and
what I did to test it. specs referenced in the video: fuel pressure (in
PSI): TBI (9-13), MFI (41-47), CMFI (58-64), CSEFI (55-61). Those
pressures are for key on, not running. When running normal range is
3-10psi less for all injection systems. Injector resistance (in ohms): TBI
1.16-1.36, MFI (11.6-12.4), CMFI (1.37-1.77). In the video I forgot to
mention it is fairly difficult to bend the spider legs of the new injector
unit so they fit in the intake holes. Pay attention to the way the
original was installed (legs going over/under the nut kit lines) and try to
replicate the original routing. Oh... and I forgot to mention that if you
have a fuel lean condition, spray quick start in the throttle body and see
if it starts... if it runs on quick start, you have proven your condition
is a lack of fuel.
UPDATE Dec 8_2011: I still have the 2 moulded fuel injector lines (new
never used) and I want to sell them... if you need these lines send me a
private message and we can work out a deal. Thanks.
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.
