as the title says i jst bought a 95 gsx. im havin a bit of trouble with it the guy i bought it off of was a tool. now for the problem when i start it, it idles at like 1500rpms then drops down to around 100 or 200 rpms then kicks back up to 1500 so i changed the plugs, oil, annd valve cover gasket cuz oil was seeping out of the old one thinking this is the cheapest way to start fixing the problem. when i drove it i hammered into it a lil bit, and after it got to like 4500-5000 rrpms it was hardly pullin and it was cuttin out real bad and the head started tickin loud the turbo was spoolin and it blew off when i shifted so it was gettin plenty of air. this is my first boosted car so idk much about it... any ideas?
my buddy thinks its the head gasket
it has new water pump alternator and timing belt greddy exhaust and type rs blowoff valve
any help would be greatly appreciated thank you

 

One: Please write legibly. Good spelling and grammar isn't that hard.

Two: Is the BOV recirculated?

Three: Have you checked for boost leaks

Four: Don't listen to your buddy.

 

Like Sebba said, do a boost leak test and make sure the bov is recirc.

 

How do I do a boost leak test and no the bov is not recirculated

 

Recirc the bov to the intake and drive it again.

 

Ok but that wouldn't cause the head to tick would it?

 

These motors tick normally.

 

Ok I recirculated the bov and the idle is a Lil bit better it's around 1200 but it still drrops down low and I noticed th valve cover is cracked too

 

The tick is the lifters they get dirty and make noise. They make a 3g revised lifter that takes care of the noise.

Try a boost leak test, www.vfaq.com has instructions how to make one.

 

Get a new valve cover too.
