122838B Posted April 25, 2007 Share Posted April 25, 2007 My 90 Reatta stalls and dies in traffic and it is getting harder to restart. Today it stalled in the middle of a major intersection in Washington, D.C. even after the car was thorougly warmed up. It then started dying when I took my foot off the accelerator. The engine service light is mostly on. A service station mechanic changed the idle air control valve and the fuel and air filters and cleaned up a lot of carbon residue. He put in fuel injector cleaner and changed the relays. He said codes do not show anything wrong. Could this be caused by a clogged catalytic converter? Does it need a fuel pump? Any advice would be greatly appreciated. Link to comment Share on other sites More sharing options...
Guest imported_blazer1997 Posted April 25, 2007 Share Posted April 25, 2007 Have your mechanic check the fuel pressure. Link to comment Share on other sites More sharing options...
Guest F14CRAZY Posted April 25, 2007 Share Posted April 25, 2007 I agree, check the fuel pressure Link to comment Share on other sites More sharing options...
Vincent Vega Posted April 25, 2007 Share Posted April 25, 2007 As the others said, check the fuel pressure. The fuel system pressure is maintained by a regulator. It is right on top of the engine. It is very easy to replace. Link to comment Share on other sites More sharing options...
122838B Posted April 25, 2007 Author Share Posted April 25, 2007 Thanks for the advice concerning the fuel pressure regulator. Just where on top of the engine is it and what does it look like. Is it expensive? I got to tell you this Reatta is not improving my relationship with my wife, what with all its recurring and new problems. It only has 57,000 miles but it has far more problems than my "Italian" 1986 Alfa Spider. Link to comment Share on other sites More sharing options...

Guest inthespot Posted April 27, 2007 Share Posted April 27, 2007 Ok.... on the picture I can see where the Seafoam port is. The seafoam that I have used is liquid that you pour out of a can. How you get the product into the port? Link to comment Share on other sites More sharing options...
Roadster90 Posted April 27, 2007 Share Posted April 27, 2007 GREAT illustration John...I also have been thinking about trying the Sea Foam, but have been / am unusre on how to apply? Link to comment Share on other sites More sharing options...
Vincent Vega Posted April 27, 2007 Share Posted April 27, 2007 Connect a hose to the vac port. With the engine running put the other end of the hose in the seafoam can. It will suck the liquid into the intake manifold. You have to be careful not to go too fast or you will stall the engine. Just a little at a time is good enough.

Guest smith356 Posted April 27, 2007 Share Posted April 27, 2007 Did this myself Wednesday after reading Gregs' post. It was very easy, but I didn't squeeze the tube tight enough first time. It killed the engine and blew Sea Foam back out of the can and all over me ! Did it again by bending the tube over and it worked fine. Put in a third of a can and then the rest in the tank. It is definately idling better now - smoothed it out. $6 and change at Autozone. Go for it.................. Link to comment Share on other sites More sharing options...
Guest mongeonman Posted April 27, 2007 Share Posted April 27, 2007 I am doing it today,hope it idles better after,i will write to give news. Link to comment Share on other sites More sharing options...
Machiner 55 Posted April 27, 2007 Share Posted April 27, 2007 Just do as Vincent Vega says. I've never done it myself. I've only used SeaFoam in the gas tank. I pointed out the "SeaFoam Port" because of statements from other posters. Another way to introduce the product would be to pour the contents into an empty spray bottle (old Windex sprayer), remove the black breather tube from the throttle body and while racing the engine, spray it into the throat. That way you would also be cleaning the honeycomb screen, the MAF sensor filaments and the throttle plate. Just my 2 cents. Link to comment Share on other sites More sharing options...
Guest mongeonman Posted April 28, 2007 Share Posted April 28, 2007 I used seafoam in gas tank and in "seafoam port" and it has a lot more power and it idles much better,when i poured the seafoam in the air intake i saw smoke comming out of the EGR valve,the metal base of the valve was cracked,i changed it and the car idles even better now,not perfect but ok.I still have half a tank of gas mixte with seafoam,maybe it is going to get better yet.

I thought previous posts warn against spraying anything on or near the MAF sensor! Link to comment Share on other sites More sharing options...
Ronnie Posted February 15, 2008 Share Posted February 15, 2008 I used a spray bottle and sprayed it right through the screen. It didn't hurt anything. I have also used the vacuum line to suck it in. I can't say Seafoam made any difference in the way my engine ran. I didn't have any problems to start with. Maybe my intake system was not dirty. I just did it as preventive maintenance.
