Silver86

Thanks for the feedback everybody, sounds like I shouldn't worry and will go out and enjoy my car. I will report back with my experiences in about a month.

I am sure you have seen the article on Car and Driver from the organizers of the 24 Hours of LeMons which says our Starquests are the worst possible choice of car for their event that anyone could ever make. I however am excited to take my Starion to some SoCal track day events (not for endurance racing, but rather your standard track day with 20min runs at a time). I have spent the last 6 months getting my Starion up to OEM level daily driver status. It has a non-jet valve head, new radiator, runs cool at all outside tempts, high flow fuel pump, only 10psi etc. I have fresh brake fluid, pads, rotors, etc. I guess my question is, is there anybody still tracking their Starquests, or have I lost my mind thinking my 29 year old car is going to survive even one track day event? Also, if you are in the SoCal area come join me in about a month! Thanks in advance.

I have an exhaust leak at the turbo to manifold flange. As you know, the available gaskets are paper thin. Will the thicker gaskets for a DSM work for a stock Starion turbo and manifold combination? Thanks!

I have installed an air/fuel ratio gauge and notice that under WOT, I go only as rich as around .76-.80. Is this rich enough or do I have a problem? (It's only the first green bar on a standard narrow band air/fuel ratio guage). My car is running stock fuel system at about 10psi, with Walbro 255 pump. Thanks!

Bandy, hang in there, if you are local to Southern California let me know and I can help you nail that b**** down, I was pulling my hair out too. Post your specific issues and this board will solve it for you. I assume you have checked for fault codes? It always come to fuel, air, spark...and supernatural forces conspiring to ruin your life!

Just to update and close out this thread, I finally tracked the problem down to improperly routed vacuum lines that kept the fuel vapor purge valve open at all times. Always turns out to be the simplest overlooked things for me.

Thanks, Scotty, injector resistance tests good, however when I tested the injector ballast resistor, it showed less than 1 ohm, should show 6 ohms. I have ordered a new one and will report back as to whether this fixes it.

Fuel injector resistor. Its the small shiny metal box with harness bolted next to radiator right in front of the aircan. Thanks

Its the small shiny metal box with wire harness bolted close to radiator right in front of the aircan. Mine apparently shorted out in recent rain and tests out at 1ohm, should be 6ohms. Thanks!

Will confirm again, but it is not when last checked

Hello everyone, I am pulling my hair out over this one and need help, almost ready to pass this Starion along but can't do that! No way! Have done a ton of searching and have looked through the FSM and tested everything I can think of. My car is an 86 running stock fuel system with new fuel pump, injectors, CTS, TPS and ISC reset. I keep throwing an 02 code, and while monitoring the 02 voltage while driving, it looks like I go into closed loop fine (.1 volts oscillating to .9) when up to temp, but after driving for 20 min or so, 02 voltage drops to super low (.01 or so) and part throttle driveability goes to crap, like it's running super lean. Of course, if I go WOT, it goes open loop, the 02 immediately goes nice and rich, and the car pulls fine. I have good injectors, new CTS, no boost leaks, have tried multiple brand new 02 sensors, swapped out the ECU, and have swapped out three "working" mass air flow sensors. My question is why am I able to go into a closed loop for a while but then it runs super lean. Unplugging the MAS puts it into open loop, and it runs super rich, and driveability is excellent (so I know it's not a mechanical fuel delivery problem.) My best guess at the moment is trying another MAS? Is it possible all three are bad? What am I overlooking? I don't want to go hacking up another "faulty" sensor connector only to find out it's not the problem. Thanks!

Recieved and installed mine in about 2 hours (I am slow). Entirely transformed my steering, my original coupler must have been especially worn (only 30 years old!) This is a beautiful piece, in form and function, instrumental if we are going to keep these cars on the road where they should be (as we all know the oem parts are NLA at any cost). I nominate BC_99 as starquestclub man of the year! Now my next request is for you to manufacture true replacement oem style injectors. I have a little stockpile of used oem injectors but am paranoid someday I will run out. Anyway, off topic I know. Thanks! I nominate BC_99

Welcome back, you have set a good example of what it means to acknowledge our bad behavior and make amends. Any interest in selling a front hood emblem? See you around the board.

Messaged you, doctor drift, let me know your paypal address and I'll get you money, thanks!

Thanks!
