3800 2 codes

[SaturdaysGS]

The SES light was recently tripped and I got Cylinder 4 Misfire, and System Too Rich - Bank 1. I assume the misfire is from my worn out AL-104's Thats what I get for being lazy and only doing the front 3.

But what about the system too rich? Could that be from the misfire causing raw unburnt fuel?

I do NOT have a MAF screen, but have one on order. This code was never tripped before when I was MAF screenless for several months. I have changed nothing on the car also.

I hated the car without the screen, hard to tune, and it could be a combo of your problems. Check cylinder 4 and change the plug. That may get rid of both, then reinstall your screen because it was not worth running without it.

You aren't kidding. I will change the plugs ASAP, and put in the MAF screen when I get it.

I bet both codes go away once you get the plugs changed. Be sure to check your wires and be sure to use the grease. I also noticed the coil packs get nasty. Might want to check the connections. A light sanding improves the conductivity and then some new grease.

Thanks John, I will make sure to use di-electric grease on the plugs, and some antiseize on the threads. I remember the coil packs were nasty/rusty several months ago and I cleaned them off.. maybe time to do it again.

ive always heard horror stories about cyl. #4.....id check that plug before you drive it again

Yes Cylinder 4 always gave me problems on my brother's car.... Gets too hot. Be sure to gap it properly as well! Are you running a 180 T stat? When I put 104s in his car and changed the Tstat to a 180 it ran soo much better.

Well.. I haven't been beating on it at all when/before the code was tripped.. and I haven't beat on it since. So its probably just a fouled out AL 104.. they do have high miles (for a colder/copper plug).

I will probably do all the plugs again as its cheap, and the front is easy as pie to do. I will have to, because I forgot what I used on the front 3's gap. Hows .054?

Yep I have a 180* thermo

Kinda off topic but not really...

How many miles can you expect to get out of AL 104. Once every year?

i was getting two months if i didnt get under boost ever..there just to cold for normal driving. and barely getting on it (winter) spirted driving will last longer i suppose. Ask Ron ive never heard of a car having as many plug changes as his car..he has bags of them id use tr-6s they are the best ive ever had..i will never go back to AL's

 

[SaturdaysGS]

Bob, how much are the TR-6's if im going to do them all, mine as well try those.

My autolites lasted (and by lasted I mean before the gap grew to big and/or are causing a random idle misfire every minute or so) about 15k give or take.. I think. Keep in mind, I run the car HARD, atleast WOT every trip. Unless its raining or snowing. If I wasn't lazy, I'd probably change them more like every 8k or so to keep them fresh, and within gap.

Also, I should gap them at what? .054?
