My car is being one stubborn mule.

-I'll start it up...everythings good - Idling at 1k RPM
-I'll put it in Reverse...RPM drops to 500
-I'll start backing out of my driveway... and put ut a put...it bogs down to like 200 RPM.
-I'll STOMP on it and I have TERRIBLE throttle reponse -> it takes it like almost 2 seconds to react to the throttle.


Same thing at Stop Signs and Red Lights...

WTF could this be?

My knock sensor? My 02 sensor? Distributor?

I've got Yazaki Plug Wires and BOSCH platinum plugs (brand new)...if that helps

'90 GXE pushin 78k miles

 

MAF?

 

distributor? cap? sounds like tune up stuff, look at your egr vaulve when I needed a tune up on my gxe I know on the egr valve would get cheery red when hot.

 

first thing to try might be to get rid of those plugs and wires and get some NGK or Bosch wires and NGK OEM (NON-platinum)plugs

 

Exhaust Gas Return Valve - Jason? How much do those run? Where is it?

I finally got my dist cap off....my terminals are pretty haggard. Kinda white and burned, so...new cap, new wires, and NGK plugs.

My MAF is good, I advanced my timing...but

BAGS told me about the idle speed. How its computerized and all....but he said on his 4th gen there's an idle air control valve (4th gen) and the screw is on the throttle body.

Anyone know if VGs have those?

 

no the EGR isnt bad, it just gets hot when the car is running rich, do a full tune up and use oem or nissan recomened parts, and Im sure they are in the FAQ's or search befor eyou ask
