The past week coming from new Mexico to texas my 05 scion was acting up on while i gave it gas, loss of power, car would shake, rpms would not shift smoothly i noticed alot of lag and was afraid of burning the engine on a 80 mile trip getting stranded on the dessert, so i took it slow trying not to accelerate over 2500rpms and prayed to god i get home. I switched out the maf sensor and ran a bit better but still had that lag, today i switched out the old spark plugs to ngk iridium laser, changed its oil cause it needed one, mobil one filter and a stp fuel injector treatment. This made my car back to normal changing gears smooth as butter and actually i gained more hp. I was getting ready to give up on my tc but i made it, i regained its love.

 

congratulations you gave it a tune up

 

God I love you.

 

It had a check engine code for misfire on cylinder #2

 

Right, because the fuel and ignition systems were neglected.

 

the ngk laser iridium's are the ones I pulled out of mine, they were put in at the factory. Great plugs too! Glad you got it fixed!!

how many miles on your tc? Wondering how many miles were on these spark plugs...

 

Im coming close to 180k already they had some Bosch plugs in

 

bosch plugs will make any toyota engine run like crap... i my self went with denso iridium

 

yeah bosch doesn't seem to agree with the toyota engines. I personally like the NGK plugs, laser iridiums.. that's what you went with. Shouldn't be another problem, that's what I like about NGK. Can rely that they make good stuff, put it in, it works well. No drama!

 

It is running really nice had no hiccups no problems accelerating, these ngk laser iridium are really nice, plus im getting better gas mileage and power

 

Very glad to hear.
