I just had this same TSIB performed on my 06 IS350. Its alot quieter now....I just had my 07 IS 350 in today for TSB 0156-08. My car made an engine rattle on cold start and they replaced the camshaft gear assemblies. Apparently this is a problem my service guy has seen on several IS because the previous gear assembly didn't maintain oil pressure within the assembly.
I just had this done to my car. Didn't notice any difference, but I was on empty and they fill up your tank when they are done!I've not yet seen a TSIB on this, perhaps since they qualify it as a recall as opposed to a TSIB? Not sure. At any rate, how much info does it give you about the risk factors with the fuel line, if any?
i'm new here and I got 2007 is350.
I had it for a little while now, but only recently finally bought an intake.
i read all over and decided Injen would be good, so i got it.
now the sound is awesome (loving it), hp and torque increase is definitely there, but theres a problem... i lost throttle response....not all the time, but sometimes when i step on the gas, seems like trany doesnt downshift and it seems like the throttle is behind.
someone told me that coming-out air is restricting that, and that I got to get an aftermarket exhaust, but i feel much more comfortable with stock one, at least for now.
did anyone ever heard of that problem and would know what to do?
maybe the hp is minor (even though they promise up to 19hp gain) I can still feel that it pulls better.......Any power gains are entirely in your imagination- no intake adds enough power to make a noticeable difference in anything but sound on the 2IS. (quite a lot of folks mistake louder for faster though)
Ditto the throttle response if the intake is installed properly (which would be the first thing I'd check- to insure there's not some small leak somewhere in the intake path from something not quite tight enough).
The stock intake already provides more air than the engine is capable of using... it's not like an after-market one now magically provides "extra" air the car doesn't know how to deal with... (that's what the MAFS is for after all).... and thus an aftermarket exhaust, while it'll also add a small few hp, isn't "necessary" for anything else to work properly.
I had it off for a few days now, cause I took it to dealer (right before the warranty expires) and had them refinish all my wheels at no charge...they look like new now.Check for leaks after the MAF. This would give an incorrect reading to the ECU and make the engine sluggish.
