1993 Nissan Quest GXE 3.0L DISTRIBUTOR??? SOLENOIDE? WHAAATTT??? HELP HELP HELP!!!?

HELLO!! My car is running rough since a month, I changed plug wires,spark plugs (ngk), air filter, drive belts, engine oil, but it still runs rough! Can my distributor be the reason? How do I test if my distributor is working properly? Does it have any inicial starting position everytime the engine goes on/off? What about the solenoide? Can my solenoide output voltage be the reason? Meaning less spark...?





I step on the gas but there is no acceleration increment (as before) and no power (even with a V6!). The car SOUNDS like it %26quot;has%26quot; POWER but when on the road it just doesnt show! The only thing changing is my gas bill (wasting more gas $$$). I try to avoid hills because its hard to go up with the condition my car is in!!



Can an EGR valve or IAC valve (or any other valve) get damaged when washing the engine with a hose/degreaser? What are some common components that may cause an engine like mine to run rough?



And finally, can it be possible (meaning the reason of my problem) the intake manifold be clogged with gunk? Or some other air/fuel/gas hose? The car has only 82,000 miles, BUT it only had 1 time replaced air filter (55,000 miles I guess) and the one that it had wasnt filtering 100% since its width wasnt the appropiate!!



Also Im thinking fuel injectors may be working wrong...I hosed them with water when attempting to wash my engine. Can they go BAD that way? I took off my battery when washing the engine...



And one more question, HOW DO I TEST a spark plug? I have one method which is by disconnecting (when the engine is running) a plug wire from the spark plug, and if the engine %26quot;stumbles%26quot; or if I hear a change in engine performance, then there is spark in the cylinder...The problem is, I DO NOT HAVE a 10K Volt generator to see the arc in the spark plug!!1993 Nissan Quest GXE 3.0L DISTRIBUTOR??? SOLENOIDE? WHAAATTT??? HELP HELP HELP!!!?did u change cap rotor u didnt say if u did timing could have jumped too did u check fuel pressure u can test the coil spark should jump atleast a half inch dist is optical water could have damadged it if it got into it check ur basics again so u know where problem is coming from iff ur useing alot of gas check ur o2 sensor reading if stuck lean comp will add more fuel same thing for coolant temp sensor which is notorious on nissans check ur connections since early nissan wiring harnessses tend to corrod injector dont useually go bad on these nissans they usually leak like i said do ur basics again test spark fuel pressure timing then if everything checks out check input from sensors tps .5-.9 at idle maf 1.2-1.5 at idle coolant temp around 3.5 at normal engine temp easier to see with scanner iff u need any more info email me1993 Nissan Quest GXE 3.0L DISTRIBUTOR???

If it only happened after you washed the motor check if the inside of the distributor cap is wet. Dry it with WD-40.
