Well i changed the plugs and wires yesterday and after i started here up it started to misfire. I took it apart again everything seemed fine, any ideas ?

 

Were the plugs gapped right? Did you cross any plug wires?

Rob

 

actually i didnt gap them what are they supposed to be gapped at, wires are fine

 

Not sure what engine do you have? They are supposed to come gapped correctly but sometimes they are a bit off.

Rob

 

its a 22re

 

I think it's .030 but not positive.

Rob

 

gapped them and still misfiring will i be alright driving it ? what else should i look at ?

 

Plug gap should be .032 But if you're .030 you should be fine... Sometimes spark plugs come bad from the box... did you drop one? Which cylinder is missing? Does it have spark to it? Are you sure the spark plug is actually sparking? I would find out which cyl is missing and test the plug / wire for spark.

 

What type of wires did you get?

 

how would i test each wire to check for spark ? / i used bosch plug wires

 

well all wires are firing i just pulled em out and they shot against the head. the number 2 wire ripped (i got stressed out lol) so i bought a new set of wires and also got a cap and rotor. After the install it ran fine fine till i started to rev it and after that it just kept on misfiring. any suggestions ?

 

Bosche ignition componenets are notorious for not working with Japanese engines. That would be my first guess. I bought Bosch Platinum plugs a few years ago and NEVER got rid of the miss until I replaced them with NGK. Use OEM Denso or NGK wires/plugs.

 

hmm has anyone else had this problem with bosche ?

 

anyone ?

 

If you could determine which one was misfiring, it would be easer to determine the problem. Once that is done, put one of you old plugs or/and wires on it to see if it goes away. If so, wire or plug. If not, maybe injector.

 

my 20r didnt miss but it ran crappy with bosch plugs

 

check injectors if efi timing maybe

 

yes. bosch belongs on VW's not Toyotas.

 

make certian you hooked the wires up right.
1342

and that you installed NGK 1233

 

my order is fine, it must be those plugs my local parts store cant get them in till next Tuesday. (i live in MI not much parts for foreign cars)
