It simply won't run right...

thepyrofish · #1 07-31-2006, 01:33 PM

OK. I'm trying to get my car(the one in my sig) to run properly. It's stuttering. By stuttering I mean constantly, sounds kinda like a miss I'm not sure. It does it at any RPM, but I don't know if I lack power or not. Car was off the road for storage so I won't be able to drive it until I get it running.

I've tried zeroing out the Maf Translator and retuning it using instuctions online, and I can tell I'm doing it right because the car is responding and improving when I do it. That miss is simply everpresent. So far, my list to try is:
Boost leak test, did one before it went into storage for the summer, but I'll do it again.
Reset BISS, I'm sure I've messed with this at some point.
Check plugs, wires, etc. Not really familiar with the Talon's Ignition system so I may as well learn it now

I have a fuel filter lying around, and I'm sure that needs to be done so I'll change it too.
EDIT: I'm also going to doublecheck the timing...

I have a datalogger, but the palm pilot is a piece and doesn't work right so I can't use it. I'll be getting a new one, but it won't be here right away.

Is there anything I'm missing here? I miss my fast car and people are starting to doubt my mechanical ability

The car was running a little rough for a bit, then one day it started doing this. If anyone has any ideas, suggestions, or advice please let me know. I need all the help I can get.

What plugs do you have in it and at what gap?

thepyrofish · #3 07-31-2006, 03:03 PM

To be honest, I don't know. They were nearly new when I bought the car so I haven't changed them yet. I know better than to trust a PO on anything, but I was lazy. I am going to work on the car this evening so I will check that as well.

Make sure you have a dealer timing belt.

That really isn't such a big necessity, it's just something that some people like for a preference. I've done many timing jobs on aftermarket belts and not a single one has come back faulty yet.

Pyrofish, what are your compression numbers?

scottsee · #6 08-01-2006, 10:56 AM

Are you missing at when ever the car is on? Or only durring WOT?

MexRocket · #7 08-01-2006, 11:58 AM

or have you checked your wires to see if they are grounding somewhere else? If they have a resistance over like .7 or something.... you need new wires, and could cause what you are saying. I had wires with a resistance of 5.0 yes... fucking 5 fixed the problem with new wires

Ok, I got busy helping my dad with some things so I didn't even touch the car last night. I'll get to it this afternoon though. I have to go borrow a compression tester and I need a ride from my sister. I hate being car-less.

Oh, and it misses all the time. From idle to redline, regardless of throttle. I'll get back to you guys later today, and thanks for all the help so far.

I may have something here...

These are the plugs, in the same order as they were in the car. 1 and 4 melted!

They are the BPR6EIX NGK Iridiums. The NAPA in my litle podunk town only had 3 6ES in stock, and didn't carry the 7ES. I ended up replacing them with cheap-ass AutoLite plugs.

I also found 2 more leaks, nothing major, and sealed them up (one was my boost guage...yet another thing that I need to re-install correctly

)

I don't know if any of this fixed it, however, as my battery is dead and my Dad's battery charger blew up last week. Nobody is around to boost me. Figures.
I also made sure all the plug wires seemed ok and were attached solidly. My multimeter seems to have been misappropriated, so I haven't checked resistance. I haven't reset the BISS or checked timing because I can't start the car yet...
I'm staying optimistic and hoping it's good now, but with my luck it's as bad as ever. I'll post again when I've got it started.

l_eclipse_l · #10 08-03-2006, 03:42 PM

Wholly shit...but that was about what I expected lol.

Should have just replaced them with the 6es instead of shooting yourself in the foot once again and buying the *cough* Autolites...might want to take them back before running them and exchange. Make sure you gap them.

thepyrofish · #11 08-03-2006, 04:31 PM

Yeah, NAPA called me a half hour later 'cause they found another case of the 6es. So I returned the other ones and bought an extra set. Gapped at 028 and waiting for someone to come home and boost me

First stop, new battery.

Cross your fingers, boys...

Okay, I'm no mechanic (yet!), but isn't the reason why they burned important?

thepyrofish · #13 08-03-2006, 06:32 PM

Yes. Yes it is. From what I read a little bit, we run the 7es instead of the 6es when we start to mod because it handles heat better? My car was probably knocking its ass off when my friend ran 87 in it too, so it may have had something to do with that. I'm going to look into it a bit tonight, as well as reading up on cams. Yay.

EDIT: Got it started. Still missing, still pissing me off. If the sparkplugs didn't fix it, and the rest of the ignition checks out, I'm assuming the melted plugs were a symptom and not a problem. Goody. I hope to check timing tomorrow.

Blackcrow64 · #14 08-04-2006, 12:26 AM

Did you check to see if your coil pack is bad? And running 87 octane in a turbo dsm is a horrible idea. 92 and higher is the safest thing to use.

thepyrofish · #15 08-04-2006, 04:00 AM

Yeah, I always run 91 or 93 depending where I'm getting gas. He only put in a quarter tank or so, so I drained most of it and made him put premium in it.

I'm short in tools at this house, 'cause I have no garage. I'll be getting a timing light and a multimeter (still can't find mine damnit) tomorrow likely, so then I'll be able to do some more. I'll just assume I can find instructions on testing the coil pack if I search around. Every other damned thing is online...
