help!help!
My 1982 280zx non turbo keeps on sputtering. When i first turn on the car it idles fine,starts up perfect and i can rev the enigine and everything looks and sounds good. as soon as the car warms up for around ten minutes is when the rpm's wont go higher than 2000. all the valves look good ive replaced the following parts
-Throttle position sensor -ignition pickup coil -ignition module -mass air flow sensor -fuel pump -electronic ignition coil -oxygen sensor -CAT any help??? |
I think this is the first major issue of all new zdriver members. You're more that likely about to hear "check your CHTS", as I don't see that on your list of checked parts. It is on the passenger side of the head, and it has a little connector that looks like an injector plug, check the connections, make sure they aren't corroded, mine were >.<
I think 3/4 of the people on this site have had the same issue. |
ecu

Between Cylinders 5 and 6, check that, unplug the connector and check the leads. (Sorry for quality) This is a very common culprit for the issue that you are having. Attachment 18741 |

It is pretty much like a fuel injector connector. So just get one for that, wire it up, and you should be good with that. ;)

did the 79have a CHTS? i know it didnt have a O2 sensor...
|
If it doesn't have a CHTS, it has the coolant temp sensor (exact same sensor, just located in the thermostat housing).

Rusty gas tank!

What's the condition of your distributor? Is the module on it damaged? When's the last time you changed your cap and rotor? Is your cap cracked or something? Before I started my engine swap I really let things go to sh!t under the hood because I knew the old motor was going away, but at one point I started getting steam near the distributor from the thermostat housing and it got the system all wet and would completely lose ignition after 2200 RPM (which was not fun on the 15 mile trip I had to get the car home that day). No spark after a specific RPM range sounds like a distributor problem to me. |
egr
Its not the fuel tank. i replaced the chts and its still sputtering. could it be the EGR?? i feel like im running out of things to check and replace...:disgust:

Does it pop and sputter through the intake side, or does it sputter coming out the exhaust? These cars also notorious for bad ecu contacts. Try cleaning the contact, and jiggling the wires to see if that helps. Do you have any vacuum leaks?
