Ok.
Everything is in place. Car started without a problem, But.....

Here is the story.
Last week when nosedrive broke I was miles away from home,so I was doing this stop n go thing.
Basically it was 2 min drive and 20 min cool down.
I never let the car to get to the end of the temperature gage.
It was like 2 miles from home when it started misfiring.
Before removing SC I checked with scaner and it was #4 and #5 cylinders.
And from time to time #1 cylinder on low RPM.

Today when I started the car it was the same story.
Same cylinders. I changed spark plugs but it'* still misfiring.

It was cold and windy here today and I spent a lot of hours by the car so troubleshooting will continue tomorrow.

Any idea where else I have to look?

EDIT: Do I have to start a different topic in 1992=1999 area?

well, cyl 1 and 4 are on the same coil, so id suggest testing it following the tech info. then post your resistance readings. could be a weak or dead ign coil.

What do the plugs look like? Fuel fouled, or dry? What type of plugs? Have you checked the wires as well as the coils that were suggested?

While waiting for nosedrive I removed #1 and #5.
#1 was dry and # 5 was wet.
II cleaned them and put back.
I didn't check #4 at that time.
After finished with SC and start a car got that same misfire.
Removed #1 - was dry.Replased with new anyway.
Removed #5 -was dry. Replaced anyway.
Removed #4 -was alittle bit wet(probably still from that last week driving) Replaced.
Started car-misfire still present.
At that point didn't check which cylinders still misfiring.
I was freezing allmost to death at that point.
Went home to warm up.

I do have spare coil packs(two of them) and spare ICM. All in working condition.
All I 'm worried if it'* nothing related with pistons/valves etc.

I gotta jump to the groccery store.On my way I will fire it up and check in dark if there is no ignition leak by the chance.

Plugs are BOSH. I know it'* crap,just that store near me didn't have any and I guess for a few days new one will be OK.

First of all, please EDIT your previous reply instead of replying to yourself.

We can't help you with this until you CHECK your coils and plug wires for resistance, and get something other than Bosch plugs.

Let us know when you're ready.

Ok.
I will be ready tomorrow.
I remember that day when driving home and on one of stops cooling down engine it was raining and my hood was open for faster cooling.
Then after 20 min I tried to start and couldnd,not even a starter click.
Obviously because battery was all wet and some other parts too.
I jump started it and kkept driving but what I think is ICM and coils got wet too and may be failed at some point,not right away.
It'* just wishfull thinking,because if this is a case it will be siolved quickly,otherwise I don't know :(

Thanks for replying and CU tomorrow

LOSE the bosch. if that parts store doesnt have either the delco or ngk plugs, then they have no business calling themselves a PARTS store.

Wet batteries, coils, and ICM'* don't prevent starts.

Well ,let me respectfully disagree.
How you going to crank engine with dead/drained because of moisture battery ?
There is a reason for that suggestion of keeping battery surface clean and dry.

Samueljackson,I t doesn't mean they (BOSH plugs) don't work from the moment you installed them.
When my original plugs were floaded because I didn't tight TB enough after replacing it with all 6 plugs from BOSH there was no misfiring on any of them.

They are installed temporarily and it'* not a cause of misfiring.
