What would I look for? I'm not even sure what they look like. The mech. want about $250 to trouble shoot.

Opps, I typed wrong did not mean packs.

It is Mercon V and it had not been changed before, 57000 miles

Transmission fluid needs to be changed every 30k miles.

Also you have additional information in this thread pointing towards the coils/boots.

For $250 you can replace all of the coils if you do your own work it is more likely that only a few are bad...

$250 is way to much money to diagnose a problem... hell even the "stealership" charges less.

but also said it is missing on 1-5-and 7. He said that one bad coil pack could screw up others by emitting radio waves.

LMAO....what a douche.

He wants to try switching them around to pin point the bad one.

You can do this VERY easily by yourself....but you need a scanner to be able to see if the "miss" changes cylinders.

I recommend(just as others have) to remove the coils and visually inspect the boots. Most likely you'll see a crack/tear and that will be your tell tale sign that your coils are fine. Start with Cylinders 1/5/7 since the Mech said he found Misfire Data on them. Honestly....I'd replace all the boots and get it over with, and also I wouldn't replace the plugs with platinum(sorry Max) because even though coppers don't last as long, your car will run/idle better and you'll get better MPG too. Platinums are decent, but I've had several instances of driveability issues with them too.

Interseting, the mech. told me that would erase them.

He doesn't know what he is talking about than. ALL OBD2 cars(96-newer) have a battery backup style memory that stores the codes AND the computer data when battery voltage is lost. This keeps the vehicle parameters intact to prevent a "relearn" process anytime the battery is disconnected, and it also stores the codes to prevent "tampering".(i.e. smog/dealer visits)

OK I don't trust this Mech.

He hooked up the scanner and took it for a test drive, came back telling me it's missing on 1-5-and 7 but the only code he says he got was p1000 (drive more). Could a scanner do that? Tell me what's happening while driving, but not give a code?

I have a scanner, but I’m still learning how to use it.

I've probably drove over 120 miles today and it is still the only code.

I am able to do the work myself, but until now I have never worked on these newer cars. I’ve owned mostly 50's and 60's cars.

I think I will start by inspecting the coils ( as described above )

I am very curious how he knew it is missing on 1-5-7
 
It isn't the miles driven, it's the "Drive Cycles". One drive cycle is a start engine, drive away, a bit of time in city traffic, and some hwy time. Then a stop/shut off engine. I believe you need a minimum of 3 (or is it 4) drive cycles to complete a code check.

I work out of this car. I must have started and shut off at least 10 times mostly city driving and some hwy (20 miles each way)and that is just today!

Am I not driving enough per cycle?
 
hehehehe...Sounds like you should have done enough! That mech MIGHT have had one of those computer code readers that he can hook up to the OBD port and be able to watch the ignition cycle....You CAN have misfires without throwing a code! Did you look at your coils/boots/plugs?
 
None(you didn't fill out a name, so it says "none", haha)......

The ECU will story MisFire data in its "history". The data could be stored from a LONG time ago if you've ever had any problems before, or it could be showing him "realtime" misfire data. Basically its a counter that keeps track every 15-20 seconds and totals the misfires up and than starts over. It than keeps an overall history of how many times a cylinder has misfired.

For instance....I had a friend with a bad coil pack(Grand-am) and his car was misfiring on cylinders 2 and 4. The counter was hitting 400 misfires in 20 seconds before it started the count over. This was the realtime data, his history data showed 9,000+ misfires on both of those cylinders.

Either way....that tech could be full of crap and trying to get some money from you.

You say you have a scanner? What do you have?

As far as the P1000 code goes.....I'm sure you've already passed the ignition/key cycles necessary to have the system running properly, so you may have some other issues.

Sorry I was out of town and my son thought it would be funny to mess with my computer. HAHA I still laughing (NOT!)

Anyway, it turned out to be broken boots on 7 & 8. Not sure why he was reading a misfire on 1,5,7. I pulled 5, everything look good, then 7 cracked.

I replaced all but 2 & 6 (someone already did) and new plugs!

Running great

Thanks all!
 
Sorry to bring up an old thread, just wanted to say good job doing it yourself and glad we could help.
