Do you have a check engine light? Does the tach jump when it misses?

My 1999 suburban is missfiring on cylinder one, changed new plug, cap & rotor, wires


You seem to have covered almost everything electrical. That leaves mechanical. Either valves sticking, frozen, or spring, cam broken. Fuel line or injector to that cylinder is the only other item I can think of. Let me know how it works for you.

Surges are not exactly fuel related so stop spending that money. Have a diagnostic done. Surges are pc related. Faulty info in most cases.

Car has new plugs, wires, dist. cap and rotor, also water pump. Sputters badly when you take off, continues to sputter until higher speed is reached. Also surges occassionally when idling. Fuel pressure...


to me it sounds like your just about to put water down your exhaust mate or your rings are binding up. I recon dump your oil and run diesel oil from now on and reset your timing belt before those new spark plugs end up in your lap.

Repaced rotor cap plugs wires, ran fine. tell


First thing I would do is change your fuel filter. Check all vacuum lines and all your wire connections. Also check fuel pump relay to see if it is faulty or if there is shorted wires under the relay or fuse blocks.

Go to Auto Zone and have the Suburban scanned for DTC codes, Auto Zone scan for free and most Auto shop will do it for $10.00 to $20.00 since they want your business cause they know most large Auto Parts store scan for free.
It sounds like you have a miss fire which can be caused by and O2 sensor or dirty MAF sensor which can be cleaned or time to replace the rotor and cap, plug wire and spark plugs.
Note that the distributor cap and rotor is made of plastic and is know to crack do to time and heat. There is also a rubber valve or screen at the bottom of the distributor that get's dirty and the inside of the distributor collects with condesation and corrode the rotor and caps too.
Good luck and hope this helps, Get it scanned and see if it's a sensor that is causing the miss fire on the hightway. If not then replace the cap and rotor and clean out the distributor if needed. Inspect the plug wire and replace if needed and change the plugs.

Keep me posted. be glad to help you out.

Surburban just died


Check to see if the fuel pump is working. It makes a whirring noise when key is turned to start. If you cannot hear tht noise. it is probably a bad fuel pump. Next check if it has spark. remove a sprk plug and using heavy gloves or bundled rag, connect plug to wire and hold thread of spark plug to ground. If it has spark. It will "spark " a bluish spark. If not, then the problem lies in the coils.or distributer . Check that all the wires are good and that they are inserted into the ditributer cap snug . Check cap for cracks also check the rotor. If cap is humid, spray WD40 into it to dissipate any moisture. Check coils (if equipped without distrbutor) . Have car scanned for free at any auto parts store to get a trouble code.
