4A FE Missing Problem

[rizy102]

hi,
have a corolla, 1.6 93. basically it is not running right and is missing. changed spark plugs, ignition leads, distributor cap, o2 sensor, but still engine is missing. checked each cylinder by removing ignition leads whilst car is on and no. 3 is the one that is not firing. i take the lead out and no change whatsoever. when i take the other ones out the engine starts stuttering etc even more.
anyone have any ideas????

ps. the engine was changed a couple of years back and instead of a corolla engine, a carina engine was fitted. still 4afe though. was running right, then one day started doing this!!!!

thanks

on #3 does the plug get wet or stay dry?

It's probably not missing, the 4afe is jsut a tiny girly little motor, get out a magnafying glass, it's probably there and you just can't see it.

plug gets wet.
also, sometimes the car drives fine. it happenes sometimes, and sometimes its perfect.
thanks

CHeck the compression.. Same thing happend to me when a valve burnt on my 4a-fe celica.

hi thanks for the reply.
shall i just go to any garage and ask them to do a compression test???

if the plug is wet when that cylinder isnt getting spark but is getting fuel. what you need to do is figure out why that one cylinder isnt getting spark or is getting spark at the wrong time. check for moisture, make sure the wires are on in the right order, and in a very dark place watch the engine bay for arcing wires. did you remember to change the rotor as well as the cap?

check wires resistance first.

[rizy102]

hi, did not change the rotor. will try that tomorow. wires are brand new. how do i check wire resistence???
sorry for my lack of knowledge!!!

with a multimeter.
