Well i was checking out the plugs/coils today...(preventative maintenance)
and decided to see how bright the sparks get... i was sadly disappointed.. they are ALL incredibly weak? are they supposed to be like that... you could barely see the spark on all the coils... (all plugs are new laser platinum)
I guess my question is are they supposed to be that weak..?

Well heres the problem... It has a HUGE power loss.. i dont know whats going on with it... the following are new: knock sensor, plugs,fuel and air filters,tps sensor(adjusted), pcv valve, Transmission, u name it iv done it...

THe power seems like its been cut in half.. i drove other maximas and they are a lot faster.. not only is it slow when i punch it.. but its slow when i accelerate also... it feels like it boggs... when im accelerating and i give it more gas it boggs and doesnt go any faster...

check each coil for resistance. does idle feel smooth or rough?

are you throwing any CEL codes?

i strongly suggest a knock sensor + harness test and a compression test on your engine/per cylinder and check all the possible vaccum leaks, i.e. upper+lower manifold gasket/tb gasket, brake booster

any oil leakage, does your car eat oil so you have to add a quart every few days/weeks?

check engine grounds, they cause so many bad issues.

If it had a weak spark, I am pretty sure the car would run ****ty and you would get a CEL.

yea thats what im saying... i took it in too and they cant figure it out... it seriously runs like crap... my buddy has a 99 contour sport (sorta similar) and it runs 10x better than my maxima...

Swap ecu's with someone or something like that. How is that alternator? How are the grounds?

you know what that doesnt sound like a bad idea about the ecu...by the way the grounds have just been redone cuz i upgraded the big 3.. the alternator is good also..
