PLEASE HELP!!!

i'm having a few problems with the car 1st off...

...it's take a few trys to start her up, it's like it take the engine a while to get fuel, or needs a new starter
... when i'm not on the gas or on the break have a loud "thoud" type of sound from rear driver side like it needs new struts or bushings (if i'm just crusing...thud, thud, thud,thud)
... also my check engine light is on...came back is as mass air flow meter. Is it ok to get a replacement off of eBay for (100.00) as dealer said part cost (987.00)

other then that I love it but I need help as you guys know the cars better then me

 

A used MAF should be okay, as long as the eBay place guarantees it's functionality and everything, otherwise it could easily be a waste of money.

Ever tried pumping the gas pedal a few times before/while trying to start it? That'd be a way to tell if it's the starter or a fuel problem.

 

how is that??? how could u tell if its a started or a fuel problem????

 

ok thanks... that's all good info, I think I'm going to be ok on the starter issue...but what about the rear end????

i'm taking her to the mechanic tonight and he will call me when he knows something

what are some good exhaust upgrade for this model?

 

do you have a sc400 or sc300

ive ran blitz nur spec's on both my 400 and 300 and have never looked back...not too loud at all but definitley give the car a somewhat-exotic exhaust pitch. sounds better on my 300 than it did on my 400....

 

thanks...do you have a link for them???
... and I found out the sound from the rear was a bad rim, so I'll be looking for a new stock rim because one of them is damaged

but I love the car still can't wait until it's sick like all of yours is
