Failed MAF '90 GS Turbo??

[dasm86]

I HAVE SEARCHED THE ARCHIVES TO NO AVAIL SO I AM HERE TO TRY TO FIND A QUICK ANSWER

I'm looking at buying a stock 1990 Eclipse GS Turbo with 90K miles and the owner said the car has had issues running correctly. I was set to go look at the car tomorrow when the owner said he figured out the problem, a failed MAF sensor. When I asked him how he diagnosed the problem he told me that he disconnected the MAF and the car runs 100% with it disconnected. Does this sound right, or would disconnecting the MAF cover up another problem with the car? Let me know what you think. I'm going to look at and possibly buy the car tomorrow.

thanks

It should run better if it is failed but it won't run right and will need replaced.

I did a little more research and found that it could be something as simple as a boost leak after the MAF. The way he described it was the car runs ok up to 2-3Krpm then runs like crap and the factory boost gauge shows it's maxed at 14psi. I'm looking to buy this car as a daily driver that has some balls so I don't have to drive my 2012 5.0 mustang in the winter. Not really planning on modifying it.

Sounds to me like it has a blown coupler somewhere. When you unplug it it puts the ecu in limp mode and runs off a pre set fuel map. That is why it runs ok with it unplugged. There is more to diagnosing the problem than up hooking stuff to see how it runs. If the maf is truly bad it will throw a cel, than you can easily check the codes.

Well that would be an easy fix if it's just a blown boost coupler on the piping. The car is clean and he says I can buy it for $900. I'm going to look at it tomorrow so I'll take a look at the piping couplers.

Also, are there typical places to get boost leaks besides the couplers? Just looking for as much info as I can get before I buy the car.

Were was this car located? I may have bought it. Same description and price. It runs like crap but the car itself is in great shape so i popped on it. Did run better with the maf disconnected, but still crazy rich.
