Starting problem

A couple times when accellerating it really hesitated, when I pressed the gas pedal down it did not take off and go, it just kind of ever so slowly gained speed, pressing the gas down harder did nothing at all, did not increase the rpm's or anything, then all of a sudden it would realize I wanted it to go faster and take off.

Could this be a MAF problem??? Could the MAF cause it to get codes and not start and have weird hesitations like this?

I would check with Budfreak/Harvey. This sounds like the torque control is malfunctioning... Maybe a crossed wire with the Q/C... Inspect all the connections for the Q/C also, I suggest asking Harvey for some information about the circuit so you can test it to be sure it does not have any internal issues. Don't think it is the MAF at this point

The slow starting issue has been happening since before the QC was installed. It has never done anything like it has the last few days though. It has never had any codes or not started.

Yeah, Tina I know you have had the slow starting issue for some time now, as your posted thread back in April of this year stated. So I think the QC issue may not be the path to solving the problem. I had some similar problems with my 1991 Honda Civic. And yes, I know, the Honda Civic isn't a Subaru, and more to the point, not an SVX. Good and bad points to that statement as well, But the issue with the Honda ended up being a part referred to as an Igniter or also referred to as Ignition Module. And being an electronic part, it seemed it got worse as time went by and was always very sporadic in it's symptoms of acting up. I am not sure if the SVX has any part like this or a part somewhat like this that could be the culprit. Just thought it might be worth mentioning to at least get all the great SVX minds here at work

I am not saying the Q/C is causing it... But to rule it out would be foolish. Considering the lagging acceleration is the torque control being used inappropriately leads me to believe that it may be causing or worstening the starting issue you have now... Did the sluggish take-off begin at the same time??

I am not ruling it out, but I think whatever is going on has been going on for a while and just finally got worse. Or possibly it now has another problem making this all confusing.

Thats my point, it may have made your issue worse... like I said, try just checking all of the connections for now to make sure no wires are touching or are exposed.

did you ever find the problem??

What the heck is the Q/C

It is a piggy-back computer built to modify line pressure, eliminate torque control, and overall improve shifts. This has been the topic of many debates but its link with the torque control leads me to believe it is somewhat related to her issues.

Well my car is still having the problem. I have had time to work on it this week and try to figure out what is causing it and i'm still stuck.

I have a car that I am taking parts off of to try to figure it out. So if you have any suggestions that would be great. I'm willing to try just about anything at this point.

The car will always start now since I swapped the crank sensor under the alternator but takes a long time to start and sometimes have to press the gas pedal down to get it started.

It also has a hesitation when taking off from a stop until you get to about 15mph or so. Then acts normal. I also noticed when the car is idle it doesn't seem like it is running very smoothly.

I swapped the little disc like sensor? that is in a bracket that has a hose going directly to the EGR valve. I don't know what this piece is called, but was told to try swapping it. After I did that it seemed like it was starting better at first then started having the problem again.

Today I replaced the spark plugs and swapped the MAF. And it still has the problem.

The spark plugs looked a little brown, not sure if this is normal or not. Pic:

We are having an SVX event here at my place, just outside Cumberland Maryland this weekend. If you can , bring it down.
YT and I can check it out with a SSM and see if we can figure it out.

It should be a great time!

I am not fully sure the car would make it there.

how far is it?

Did you reset the ECU when you swapped the MAF? I would think that to be a fairly important step.

Are you sure the MAF you swapped for was good? I really think the MAF has something to do with this problem.
