Hi Guys,
I am working on an 85 car. I bought it with a hurt motor and and put another motor in. I used parts that came on the car (intake, exhaust, chip(azzato), etc).
Motor
[FONT=PrimaSans BT,Verdana,sans-serif].040 400 with 2 valve relief flat tops, forged, -5.4cc, molly rings
As Cast TFS 195 heads
Comp XFI 268 Hydro FLAT tappet cam with 1.6 (224/231 at .050, .520/.515 and 113 lsa)
Edelbrock base, Superram intake, 52mm tb, 24# injectors[/FONT]
1 5/8LTs with X pipe and magnaflow mufflers, 2.5" dual, no cats.
It has 1 5/8LTs on it with no cats and off road exhaust. It still has the stock 1 wire 02.
The Evap canister system has been removed from the car. The evap line leading from the engine bay to the tank has been capped. I noticed the fuel filler cap is vented. Even so, I still get a lot of pressure when I open it to fill up. I tried reliving the pressure (open the cap) before starting it cold and it had no effect on how the car runs.
I capped the PCV system to run open breathers. I have a bit of cranckase pressurization so its pulling some oil into the pcv. I did a compression test, all cylinders come up dead even and good. Ring clerances are failry loose, .025 and .028 or so.
The car runs like crap until it reaches closed loop. Then it runs all right. I have noticed lately I do loose vacum for my brakes after long idle times but I can not find a vacum leak. Before I removed the pcv system, the car did run a little better cold, but not great cold.
I have gone on a long highway trip with the car recently, rain fairly well.
Could it be my O2 sensor failing due to a long highway ride like that?
I did not think 02 surved any purpose until closed loop.
I am not sure if I should put the pcv setup back on to try it, but I doubt that's my problem. I am more worried about the evap setup and the fuel system.
The fuel pump is a new holley unit, ran about the same with the stocker.
Thanks and am looking for any suggestions. Can I get software/cable to scan this car? I am having a very hard time finding anyone locally that will touch an 85 tpi car as far as tuning is concerned.
Thanks
