Hey Guys,
Just went through the ordeal of replacing the FPD. What a pain! In the process, I broke a OMP line at the nipple, so I replaced both of them. Another major pain! While I was in there, I pulled the injectors and had them cleaned and flowed. Also replaced the insulators and diffusers.

Finally got it put back together today. The good news is the car started right up. The bad news is that it idles very rough (like on one rotor), doesn't really want to rev, and great clouds of smoke billow from the exhaust. The smoke looks pretty whitish to me, which would indicate coolant--possibly a very bad thing! But the engine was rebuilt less than 20K ago and ran smooth and strong 3 weeks ago when I pulled it apart to replace the FPD.

I'm not getting a CEL and all the vacuum hoses that I can see are living where they're meant to.

I'm afraid to run the engine for very long this way... I really don't want to do damage.

With all the experience out there, surely one of you has had this problem and figured it out. Any ideas?

Thanks!

Cheers,
Tom

 

Check and see if the map sensor is plugged in, and the vacuum line hasn't came off.

 

This is what I had when I first started my car after doing that job. Mine was caused by the injectors being a little stuck still after cleaning.

Idling it like that won't hurt it, although if it's flooding it may make it harder to start next time. Let it run and warm up for a while. You might also want to pull the UIM and drumbeat the injectors to make sure none of them are sticking. I used a 9v battery and some wire to individually click the injectors and make sure none were stuck.

Thanks for the ideas.

Dave, I think I recall reading the thread about your sticking injectors... I hope it's that simple.

It's off to the garage to see if I can make it happy again!

Cheers,

I agree, sounds like lots of fuel!

When you restart it go see if the smoke smells sweet, if not it's not coolant. I know when I deflooded my car it smoked just like you are describing for at least 5-10 minutes, needless to say my neighbors were NOT happy . Also when I finally figured out my car was burning coolant, at idle the smoke cloud was not very big.

 

Well, you guys are all over this sh*t! Sure enough, even tho I carefully eyeballed everything, the line to the MAP sensor had pulled loose--likely when I was reattaching the vacuum line on the intake elbow.

Hooked that baby back up and started the car: voila! It took a minute to clear the accumulated fuel, and she's runnin' fine!

Thanks a ton! It's awesome to have a resource like you guys!

Cheers,
Tom

 

The map sensor pop off helped make the 3rd gen seem less reliable - thanks to the dealerships not checking it and thinking, oh hell it sounds like it's running on 1 rotor (which it does sound like) and just chauked it up as a failed engine.
