What size and type of plugs are you running in your vehicle. If you are running spit fires they make everything hotter and are known to cause this problem especially if not gapped correctly

Using too much fuel


This could be a lot of things. Start with the basics. Since it is dark right now, if the car is in a safe area where there is little lite, raise the hood and start the engine. Do not use a flashlight, but look under the hood where the spark plug wires are and the coil wire. If you see what looks like sparks or a soft glow coming from the wires, they are bad and need to be replaced. Do not attempt to touch the wires as you'll get a bad shock.

I just changed a set on my car and gained 3 mpg.

If that isn't it, look for any loose vacuum hoses under the hood using a light. Clean the airfilter and check the spark plugs themselves to see if they are worn enough to warrant replacement.

Good luck

Truck had a very bad idle, code 300 multiple misfire, I changed the plugs, wires, distributor shaft, cap, cam pos sensor, crank sensor and the computer. Truck will start and idle fine for a few seconds...


What year is your truck? if it has a "vortex" engine in it then I would suspect the fuel injection system. The Vortex uses a spider web design with a central block and distribution liners that clip into the head. the tips are known to clog in the bores. Take the whole spider web off and spray the tips real good with carb cleaner and then clean the bores before you put it back together.

1998 gmc jimmy,about a month ago,I changed plugs wires cap and rotor and now it is runnniun ruff,mising out on acceleration shakes @ 2000 rpm.ran good for a month.


If a random multiple misfire code appears , and electrical system checks out Ok, need to do a fuel pressure test at the fuel rail (Drivers side) if checks out ok, it very well can be sticky fuel injectors.If injectors leak by can cause to much fuel dispursed into engine, sometimes a bottle of lucas fuel injector cleaner will do the trick, opens up the poppets (injectors) although the (Spider Injector) has an electrical pulse that is supplied from the ECM (computer.) The spider injectors definitely go bad some sooner than others! Not a pleasant job also an expensive job if u are not doing it yourself! If your vehicle was fine before this started happening go back over everthing u have done, check each wire out with a noid to see if spark is correct ( A noid plugs into end of the wire that goes onto the sparkplug, check each wire one at a time, u can purchase a noid for this vehicle at your local autoparts store) Not saying this is definitely the problem, there are many things that cause these problems,crank sensor, cam sensor, tps mass air flow map sensor intake leaks and vacuum leaks etc etc,u can check for leaks by spraying down intake and vacuum lines with a can of carb cleaner, look for a change in the idle when u are spraying it down How do we know? been thru it all to often! GOOD LUCK! 1998 GMC Jimmy 4.3 Liter Vortec V- 6.

My jimmy wont start have 58 psi of fuel pressure good spark but the spider injection wont open to spary the fuel brand new 280 bucks for it have checked grounds two broken one fixed those still no start...


check your ecm-ign fuse.if it is ok check to see if you have power to your spider injector.if you have power, you either have a bad computer or a bad connection between the computer and the inj.do you have spark??.if you have no spark check your ign module or bad connection at the ign module.i have seen that before.

How do you change the glow plugs and relay in a F350 1997


Hello, here is the proceedure. Any questions please ask. Good luck. CAUTION The red-striped wires on the 1994-96 DI Turbo engine carry 115 volts DC. A severe electrical shock may be given. Do not pierce the wires.
  1. Make sure the ignition switch is OFF.
  2. For 1994-96 engines, remove the valve cover.
  3. Disconnect the wire connector from the glow plug.
  4. Using a 10mm deep socket, with enough clearance as to not break or bend the wiring connector, unscrew the glow plug from the manifold.
To install:
  1. Place anti-seize on the threads of the glow plug and screw it into the manifold.
  2. Tighten the glow plug to 12 ft. lbs. (16 Nm).
  3. Plug the wiring connector.
  4. Connect the negative battery cable.
  5. For 1994-96 engines, install the valve cover.
