I think most people try this, but nah... it doesn't work well. Just replce them and be done with the problem.

Consider buying two new plugs (if not a whole set) at the auto shop. A friend of mine spent $70 at the dealership to diagnose a cracked plug. Crack would widen after warming up causing hesitation, shaking, no power, the works. The cracked plug was brand new btw. So, "the plugs are new" doesn't eliminate them as a potential cause.

Always suspect the recently replaced part first (at least that's what I do).

aziankings i think your on IFX too. and I feel like your problem may be injectors as well.

I have some for sale, hit me up on aim - robotsdobreathe

If the injector for either cylinders 2 or 3 is out, the unbalanced load on the crankshaft usually won't be enough to make the motor shake. If the injector for either cylinders 1 or 4 is out, that will make the motor shake and sometimes it will shake so much that it will trigger the knock sensor and you will notice a much more extreme power loss...

that makes sense, thank you i didnt think of that, i had cylinder 2 out w/ mine

One more important tip for you.

When you get the new (used) injectors.. Make sure you put new O-rings on them! You can get them pretty cheap at the dealership or a parts store. It's very important as the old worn out seals can cause leaking... heck a lot of times they actually rip when being re-installed..

[White Comet]

^ true but be careful what o rings u get. we put new ones on my friends car and they were crap, they almost fell apart in ur hands

[aziankingz]

which o-rings do you guys recommend?

[White Comet]

i just picked up whatever brand pepboys has. seemed to do the job nicely

[aziankingz]

well this weekend i had a nice long 4 hour drive and it seems as though the car acts up randomly as i first started..it was fine..then after a few minutes of driving, it would start shaking again and theres a loss of power. After driving for a few minutes, the car just jumps and i can hear the car sounding normal and the throttle response is great!...but once i slow down to go pay for a toll and need to get back to the required highway speeds..the engine starts shaking and the loss of power kicks in again, but would again run normal after a 10 to 15 minutes of driving!! would this be the cause of a bad injector(s)?

Just replace your injector and quit posting about it already.

Asking the same question over and over again without doing anything about it is just nonsense.

Check your timing.. Have a buddy come by to help you. Loosen the two bolts on the distributor and have it idle.. turn it one way or the other if the revs pick up good.. but if it starts to fall on its face you went too far.. thats the easiest way without a light. then rev it up see if it revs ok without wanting to die.

uhhh if u wanna be safe, use a light

Truth.I agree 100% I was just stating the poor mans way..not always the best ha

[White Comet]

its just that u can really f*** sh1t up by guessing, and lights arent that expensive
