Hello VolvoForums, my car is having a really severe issue and runs poorly due to this issue. I've been searching in forums for awhile and still cannot find a solid answer to fix my car.

I'm not financially capable (anymore) to take this car to a dealer and let them dry my resources with no guarantee of curing this. Did a lot of DIY checkups with a bunch of my (more experienced) friends and we cannot find the correct answer for this.

OBD Scanner is saying that all my ignition coils are not working, they're not even 6 months old yet.

Here's the rundown of what I've done so far for this car:
---Rough Idle but runs well---
Replaced Ignition Coils (all 5) (Oct. 2016)
Replaced Spark Plugs (all 5) right after
Replaced Fuel Injectors (all 5) (Nov. 2016)
---Started Messing up like this after this point---
Replaced Fuel Filter (Feb. 2017)
Replaced MAF (Feb. 2017)
Replaced ETM (Mar. 2017)

What would be recommended for me to do (or wait to do it) for this car for me to be able to drive this for a long trip? (graduating from college)

Watch this video to help you understand what's going on:

 

Is the throttle new or used? What codes do you have?

 

it is a used ETM build 2012 (eBay and matched my model)

I don't know the code but it is a ignition coils issue. All 5 of them.

 

You're going to need a dealer to try a throttle reload software.

Without codes, it's hard for people to help. If all 5 coils didn't work, the car wouldn't run. If the codes are for misfires in each cylinder, that does not necessarily mean the coil(s).

 

I'll try to get the code again and post it here maybe tomorrow or sooner. I should've asked for the code. The guy in O'Riley's only told me "All of them are showing ignition coil codes" because I was distracted I didn't think about asking the person in charge.

 

Yea give us the codes ok - until then do these "FREE" checks inspect all vaccum lines visually and by feeling/squeezing them with your fingers to check if you can find a broken one or if they come loose - do all of them ok and don't forget the one under the intake manifold and the plastic thick turbo hose - do this with a cold engine so you don't have to worry about burning yourself - report back of your result

 

You could get a scanner that works on Volvo I am using this Scanner

and put it in you can use throttle cleaner but not brake cleaner bc it has oil in it ok

 

I wouldn't trust what the guy at a parts store says. All they do is read codes. There is a difference between that and actually diagnosing them.

If you have warning lights, you can have them diagnosed for free at the dealer.

 

I'll be checking the codes as soon as I get off work. It's kinda dangerous to drive since it doesn't drive very well. (won't go above certain RPMs)

How would I check for vacuum lines?

Let's see what I can find through this checkups.

Thank you!

Yeah maybe I should just go straight to the dealer. I just don't like how much they would cost me and God knows if he will ask for money just to check. (Graduating student here lol)

What are the symptoms for ETMs without reprogramming? would it run at all? or would it do what it is doing with mine?

 

The symptoms would be just like the ones you have.

What dealer is near you? Volvo has a program that offers free diagnosis to customers for warning lights.

 

My car won't go above 15 mph and dealer asked for $200 to reprogram. $120 for labor + $80 for software. 😂😂😂

I'm too afraid to go today to check the codes without a tow truck or something. It won't go past 15. My other alternative would be buying an OBD reader myself

I'm going to try replacing the MAF with my old one see if there's any differences. The problem came up after I replaced the MAF and the fuel filter.

 

My car was running like crap and this is what I found out to fix it
* The vaccum hose under the intake manifold had a big split in it I found it by squeezing it and the rubber was pulverized on the outside bc of age and heat - replaced with a Silicone hose (9mm/0,4inches ID)
* 2 of the COP rubber boots on the spark plug where split could only find out by squeezing them so I replaced them - but you have replaced yours already
* Changed the MAF with new and Volvo did not like that.... Cleaned the old one and put that one in
* Changed out the Spark Plugs

Car is Rock Stable in Idle now

 

I'm going to ask my friend to help check those vacuum lines to check for tears.

I'm waiting for the security bit for me to open the new MAF with the old one. See if it change something. The MAF is one of the thing that I recently change and made it the way it goes right now. I'll check if the MAF causes this craziness.

Spark plugs are coming in the mail. I'll see what happen after I replaced them.

I just feel like something must've gone wrong when I replaced the maf and the fuel filter

 

My money is still on the used throttle.

 

Reprogramming you mean? I'm totally going to reprogram ASAP when I get money. $200 is pretty much a giant hole in my student wallet.

 

Reprogramming $200 well you better see to it that you get Total CAN Update in that price too !

 

They even told me "if it doesn't work or didn't help at all, the $120 labor will still be charged and non-refundable"

No mercy for bottleneck owner.

 

Why did you go on a "change parts spree" when you did not have a OBDII reader and/or advice from here ? It was ok to change out the Spark Plugs and Fuel Filter - see you have not changed out the Air Filter do that ok but the rest... MAF should have been cleaned first
same goes for the Throttle Body (ETM)

 

You can't. And what would that fix?

 

The reason why I decided to change fuel filter and MAF because I checked under, and the fuel filter is corroded. MAF was my first step before getting an ETM replacement, which I did replace my ETM because I do have symptoms of an old and bad ETM.

So even putting a new ETM and MAF it's still giving me this problem.

When this whole thing started, I took my car to an auto shop and have them check my codes. The guy at the desk told me that he's seeing multiple codes that lead to ignition coils issue. Which doesn't make sense since my ignition coils are under 6 months old and it's impossible to have issues with all 5 of them.
