Re: spark plugs and wires
When you replaced the plugs, are you sure that they were gapped properly? If not, double check that and also whether they seated properly- also put anti-seize compound on the threads in case you failed to the first time. Also check the fit of the plug wires to make sure they attach to the plug properly. When you pull them off you should hear a little popping sound. If the vehicle doesn't idle smoothly, you will need to confirm that you have not put the wrong wire on th wrong plug. Make sure you remove one plug and one wire at a time to avoid this. Check the fit of the plug wire at the distributer end as well.

Try spark plug wires.. Pull off one spark plug wire at a time to see which cylinder is not firing. When you find one not firing change the wire to another plug.. both ends dist and plug end. If problems travels to new location the plug wire is at fault. if it does not travel there is something wrong with that cylinder. Could be something as simple as a fuel filter. R22 is one of the best engines ever.
It's something electrical or electronic . Check for spark after it stalls an before it cool's down ! Pull a plug wire an buy a spark tester an install the tester on a plug wire .Have someone try to start the vehicle . Could be a crankshaft position sensor . If there is spark buy a fuel pressure tester an test the fuel pressure . Have the vehicle hooked up to diagnostic scan tool ,check engine sensor data parameters .
you need a person to do , diagnosis. since it is repeatable, it can be found. Ill presume you can not save the stall with a fast acting right foot, !!! one can drive with a timing light attached, trigger taped down and see if in fact spark did go away. there are only 3 fail paths. G16B engine , MAF based. MPI motor. lost of compression hot. 98s have solid lifters , skipping the 60k mile service invites this failure. as does a snapped cam belt. do the service. lost spark hot. (a tune up, cap,rotor,wire-set, spark plugs) lost fuel (lost fuel pressure ) do a full fuel pressure test. do at least the 5 tests, listed here. http://www.fixkick.com/INJECTORS/pump.html
one bad spark plug will give you a miss. 8 bad spark plugs could cause your symptoms, but I would be checking fuel pressure, and throttle position sensor signals. If all your sparkplugs were bad it would run lousy all the time, not just when you hit the gas. Also, if you are going to change the plugs, change the plug wires as well.
did you just replace the plugs or replace ignition wires, rotor, and cap (or) ignition coils if applicable? and you check whether its fuel or spark problem by running the engine and taking the plug wire off the spark plug and seeing if there is spark and noting any change in the engine, if the engine runs rough(er) or stalls then you know there is no problem spark related with that cylender, if no change occours when you take the plug wire off the plug then you know there is either a no spark condition (you will be able to see if this is the case) or if there is spark and it is a fuel problem. self explanatory, if everything you test for passes then you probably have internal engine damage. recommended that you use rubber grip pliers when you take the plug wires off while the engine is running, do not ground yourself. Hope this helps! Joseph.
When was the last time you changed your plugs wires ...spark plugs ...rotor ...and cap ....how about your fuel filter ....and air filter ect ....do you have coils ?if so ...maybe they need replacing too ....
light flashes when comp. picks up a skip pull code and it will be po300 random miss p0301 p0302 p0303 p0304 all are for that # cyl that has the miss best bet change wires and plugs check for oil on wire to plug end in spark plug hole leaking valve cover gasket or spark plug tubes...
