I own a 90 TII and im having a few issues...



1)One of my headlights stopped working but the brights work on that headlamp.Is this a connection problem or did the headlamp go?Where can I get a replacement from?



2)Whenever I let of the gas there is a strange rattle that sounds like its coming from the middle of the car...maybe the trans.Anyone else have this rattle?What do you guys think it is?I know its not the exhaust system it was just put on and its done it before hand.Im pretty sure when im in 4th gear the rattle stops for some reason...i'll go take a drive in a lil bit to make sure it stops like I said in 4th.



3)Boost issue...



-Apexi Power Intake

-Custom 3" full exhaust no cats

-Mechanical boost guage



That's about all that would deal with boost.



It doesn't run the full 8 lbs of boost its supposed to.Something electric must be messed up.



In 1st it runs to 5.5lbs

In 2nd it runs to 5.5lbs

In 3rd it runs to like 6 lbs and stays

In 4th on the freeway it goes immediately to like 7.5 lbs and stays there,doesn't creep.

In 5th maybe like 6.5 or 7 lbs again (I haven't had it at like 6k in 5th gear though).



Anyone know why it runs immediately up to 7.5 in 4th,but won't do that in any other gear at all?It's stopping right at 5.5 lbs before,where the wastegate is mechanically sprung.It's really really odd...and I don't think it's creeping which is odd.

your headlamp is out, buy a new one, they are 10 bucks at schucks.



and chances are your boost guage is messed up. try more than one guage and make sure its on a good vacuum source with no kinks in the line.

1. already answered, mine did the same thing when one went out. You can convert to some decent h4 housings and bulbs now, or just find some good replacements. 10-30 bucks.



2. Are you sure it's not your exhuast? Possible transmision mount....if it was the front rear differential you'd hear a clunk everytime you shift into gear.



3. what boost guage are you reading this from? You could rip off the stock electric boost controller and go with a profec b....they're getting pretty damn cheap now on ebay.

I'd at least jack the car up and try looking for stuff that might rattle under the car. That always helps.

I'd agree the rattling is most like a transmission mount. A way you might can tell (but not a definate no, but a most likely yes) is to look under the car. See on the undercarriage where the drivetrain is under? If it's shiny up there anywhere, as if something round was rubbing it, that could be marks from the drivetrain rubbing and wearing under the body of your car, which would most likely happen if you had a bad transmission mount.
