22RE issue.

[marvis]

I just put another 22RE into my RA65 celica so I can take my time with a 7AGE build.

I thought it was going to be easy and no issues, but I got this..

I unplug Number 1 lead and it runs the same.. It is getting an orange spark? Which I'm told it should be blue, but number two is the same.. 3 is a little closer to blue..

Compression is the following:
Cylinder 1 , 2 , 3 , 4
Dry, 200, 180, 185, 160
Wet, 210, 190, 190, 170

Any ideas?

Thanks,
marvis.

buy new plugs already.

did you check to see if the spark plug isnt fouled up? orange spark isnt a bad thing. the most importnat thing is that there is spark there. if your missing on that cylinder and the compression is ok, more than likely its a fouled or faulty plug

change plug from cyl 1 to cyl 4 then chuck cyl 4's plug in 1. that should tell you if it's the plug or not

I swapped the leads and plugs and they do the same thing.

Have you made sure you have reconnected all your earths on the head and block correctly?

[marvis]

Pretty sure Would that make just number 1 not work but? I can get the car running easy.

i have seen snapped valve springs do this. take the rocker cover off and turn the motor over by hand and make sure the valve is opening and that there is no movement in it when the lobe is starting to push it down.

it will miss with a broken spring but will still give good compression.

out of hundreds of missfires only seen this twice but worth a shot
