Bought!!!!

 

So, retune was done last night. Before the tune, the car would sometimes stay revved up (around 1500 RPM) and just sit there. After the tune, it was fixed... or at least I thought it was. It was fine on my test drive last night, drive to work this morning, and drive home this evening. But, when I went to lunch today, I started the engine and sat there until it idled down, then I did a quick rev (just love the sound of that intake) and the engine VERY SLOWLY revved down from 3k to normal. Any ideas? What had previously happened was that I put the car into park after driving and it would just rev up to 1500 RPM and sit there, so this is different.

 

Did you have to modify the E320 engine cover to get it to fit your XFire?

 

Only slightly : you have to remove a bit of plastic from the front to clear the radiator hose ( bench grinder ), and make a small cut on the driver's side for the vacuum line.

Hint : drill a 3/8" hole about 1.5" up, then use tin snips ( or hacksaw ) to remove the plastic ( for the vacuum line )

 

Well, I guess that I have learned that I need to read and investigate a little better on my own. That auction was for a V8 engine cover, not V6. Found out when I went to put it on my car. Mehh

 

I've posted a few pictures of my issue with the revving. This happened as I was leaving work to come home yesterday. I started the car, it revved higher like normal until it had warmed a little, a few seconds, completely normal. Then it revved down. Take off down the road. A couple miles later I go to slow down and the car feels different. It isn't the brakes themselves that feel different, it is like I can feel the car pushing to go forward when I am trying to slow down. I put the car in neutral, viola, car revs up to 1500 RPM. Put it back in drive, proceed home. These pictures were taken in my garage once I got home. The ones where it is revved up are when I pulled in the garage. I let it sit for a few minutes and it stayed that way. So I shut the car off, then started it back up, and the tach was pretty close to normal when I restarted it (shown in picture.)

Any ideas? I email the person who did my Eurocharged tune a couple days ago and have yet to receive a reply. I checked the brake booster, valve cover, and the t-like vacuum hoses and they all seem fine. The brake booster vacuum hose is having to bend just a little bit around the MAF sensor on the new intake, but it seems fine.

 

Sounds like air leak either at TB or MAF. Have you done a throttle reset? Do that. recheck gaskets and hose connections.

 

I have reset the throttle a few times since installing it. I'll run through and check connections again. Anyone have a specific place where they think the leak would be according to these symptoms? I really don't want to have to completely take it all off then reassemble it if there is a specific one that might be causing it.

 

The TB "O"ring delt me a lot of misery, but so did the flat seal around the MAF where it slides on to the TB. I pulled that off and put just a thin film of vac grease around the flat gasket, that solved my problem. When you do the "Throttle Reset" you do need to go out and drive it in a performance way, as it learns how you drive.

 

Every time I drive the Crossfire it is in a performance mode, haha! I didn't have a single issue with the o-ring when I was replacing it. Maybe it went too well! I just put a few little dabs of a sticky grease on it and it held the o-ring in place. I'll check the MAF sensor first, as it would be the least hassle. Thanks.

 

Decided to chase down all the vacuum tubes that connect to the TB. Found one, come out of the T at the top of the TB and comes midway up the drivers side of the engine to a sensor on the front fender area. It had come out a little bit. I could see the ribbed area that holds the fitting. It was still in, but very loose. Hopefully that was the culprit. I'll find out soon.

 

I was going to say, check those hoses. Somehow many of us seem to overlook or miss the hoses coming out when this mod is done. Don't feel bad, I did all of them, "O" ring, Gasket, and hoses.

 

Drive it some today with no issues, hopefully all is well. Now, time to wait until the right engine cover arrives. And to sell the V8 one I bought.

 

Well, I have driven it every day since the 16th with no issues. And, today, it happened again. RPMs up to 1500 when it should be idling, only happens after it has been driven. If I turn it off, then start it up, everything is fine. Then drive it around, revs up. Checked the vacuum line that had come loose previously, it is fine. Guess I need to take off the TB and reseat it.

Pain in my rear!

 

I took the TB off Saturday and reinstalled it. It looked to me that it had a pretty good seal, and I am pretty sure it got another good seal when I replaced it. Ran good all day Saturday. Then, Sunday it did the revving thing again... really annoying. I revved the engine up to about 4k and it took about 30 seconds to slowly float down, then it sat right around 1500 RPM until I turned the engine off. Then started again, it was normal. I really don't thing the TB is getting stuck, as it moves very smoothly, and snaps back shut by itself when manually opened. I thought it could be the MAF sensor, but would that not give light on the dash? Then again, it ran completely fine today.

 

Hey Shatteredhourglass,
I am starting to get the itch to do something to my N/A car and have a couple questions for you and/or the forum if you don't mind.
How's the "after" from the upgrade and Eurotune? Has your mileage (mpg) suffered?
Is the car noticeably faster? Do you have any idea of the HP increase? How much did it all cost and was it worth it?

 

Hello,

I love the car after the upgrade. It is a completely different beast. I actually have not done any major highway driving since the mods, so I can't really tell the mileage. My mileage in town is horrible, and always has been. I get right around 17-18 mpg in town, and that is what I got before, really. The car is obviously different, and noticeably faster. I do not have any empirical numbers on the HP, I would say, by feeling, more than 5, less than 20 from the tune, throttle body, and CAI together. In total, I spent right around $500 and I believe it was incredibly worth it. It was a project that I really wanted to do, and it was very rewarding!

 

Sorry, I guess I missed this post. The description said "E320", that is all I was going by, there has never been a 3.2 liter V8 to my knowledge.

 

It's no problem. BTW, if anyone needs a V8 cover, I still have it!
