One thing to point out is that this started happening before his conversion to SD. Sorry about the phone call Ryan. It sounded like you had a thought but my phone died and I was out with the kids.

As stated, my problem very similar to this was my MAP sensor. I was feeding it excess amounts of meth.

 

Are you still running an EGR Valve?

 

Day 2 update: new spark plugs installed and a definate improvement.

Start up: no issues to report

Idle issues: Died once at a stop light

Strange acellerator issue: occured twice including one stumble at ~40mph

TPS: Removed during idle and rpm's jumped to 2K which indicates it was searching for the idle, but did not stall or die.


Info request: Does anybody know what the official means to test an ignition coil is? I'm still under the 60K warranty so if its ignition coil then it should be covered.

 

Go to Andrew's tonight and use his RR's coil to see if it's that.

I will also come over and make fun of you

 

Hey Ryan this is straight off the internet:

A standard car’s distributor ignition coil can be tested by checking the ohms reading. Ohms can be read on a volt/ohms meter. Ohms is a unit of measure for the resistance that a wire or coil has. Ignition coils should be measured on the primary coil between batt and tach terminals. The batt is the coil ground. To check the secondary coil, check the ohms between the batt terminal and where the coil output wire plugs into. If the ohms read zero the coil connection is broken and the coil is no good. An open coil reading zero is the usual culprit of coils. Don’t test through the output wire though. The primary coil should read between .7 ohms and 1.7 ohms, if outside this range replace it. The secondary coil should generally read between 7.5K ohms and 10.5K ohms. If the ohms are not within the specified range for that paticular car, replace the coil. Coil resistance will also change and vary if the coil is hot or cold. This a generalized ohms range that fits most distributor coils. Another thing to remember is that sometimes a coil will only read bad after it gets hot. It may work intermittently after it gets hot also. Coil packs will generally read around .3 to 1.5 ohms on the primary side and 12.5K to 13.5K ohms on the secondary side. These figures will get you reasonably close to where the coil’s ohms need to be to work properly

 

His RR is a VIII, the coils wont work from my understanding.

Also, you should be making fun.... of yourself. You didnt even pull on me and i've got a boost leak and only put down 325whp. Go fail yourself in your own fail thread!

 

Thats the main problem, is that its so intermittant that it will be difficult to test, and the darn things are hotter than Shane's mom on stripper pole sunday after a few miles.

I'll give it a shot when cold and see what she returns.

 

Wow, Ryan, talk about fail.

First, his RR is a 9.
Second, 8 & 9 coils are the same (boots are different cause of different plugs)
Third, I didn't race your broken evo cause I would beat the crap out of it and I already feel bad for you because of how ugly you are.
And lastly, my mom strips on Saturday. You should know that cause you are her biggest customer!

 

^ "Stripper pole saturday" just didnt have the ring to it. OF COURSE we knew she strips on Saturday! How could we not? What, with the groupon's and buy 1 get 2 free flyers that have been circling the meets.

I keep forgetting the RR is a IX because of the VIII seats and lights. It is my mistake. May your mother console me this weekend.

 

I'll remind her. LMAO!

Yeah, his RR is confusing... Are you going to Andrew's tonight?

 

Sounds like I need to come up and look at tune a little more in addition. I didnt look at the TPS to see what it was doing but if its out of its range it can make the car unhappy. I have seen bad idle motors in VIIIs but no IXs yet. Have you adjusted the BISS at all?

aaron

 

I seem to recall you adjusting the BISS after she came off the lift (the evo, not Shane's mom).

Was there anything with injector cycle that looked out of sorts?

The TPS acted as anticipated when it was pulled off during the idle period in the garage last night.

Andrew has been kind enough to allow me to swap coils with his spare evo tonight. If it runs without issue for a few days then we have our issue!

And then a quick trip to the dealership (partial joke as the nearest dealership is 100 miles round trip) to get it covered under warranty and a X month wait for parts.....

 

Day 3 update: Car is dead. But it wasnt the coils!

After swapping the coils at Andrew's house the car broke down about 4 blocks away. A action-packed push start later and we limped it to his house where it sits next to his retirement community bus (not joking).

Andrew has been kind enough to swap over his 4-bar map sensor into my car to see if that is the culprit, then we'll check the o2 sensor.....

This is becoming quite frustrating. Especially as the car hasnt thrown a CEL.

 

Enough talking about Shane's mum already. Geesh.

And I thought I saw a bus in his yard when I was out walking Rose. I was like, wtf? And I saw a blue car, but couldn't tell it was an Evo from far away....

 

I always wondered how Andrew pulled so much 'tang from "Lonely Meadows." now I know!

BTW - when you said you bought a bus with a 454 you failed to mention it as a retirement community busy, Andrew! hahahaha!
