Well I fired up the RX7 last night, and let it run for a little while. the car will not idle after it warms up. I've been doing all i can to correct the issue but its still not working. The only way I can keep the car running is if i turn the idle up to lik 1100-1200, otherwise it seems as if the car is getting too rich and killing itself. I have seen a few posts around here that are relating the engine runnign way to rich at idle and throwing the knock sensor code. I am currently getting code 5 (knock sensor) and I cannot fix that issue. I did the continuity test between the harness and ground and everything works. The car was not throwing a code before i swapped in the Atkins block.

I did notice when it is idling at 1100 or so, there is alot of black smoke coming from the tail pipe, this is also whats leading me to believe its running really rich. From what I've read on here maybe the air pump is maulfunctioning? The connector broke on the air pump so I had to take the two wires, and manually connect them to the air pump. Its possible these wires are switched, but I wasnt geting an engine code or anything, so I havent played much more with this idea yet.

Moving onto getting hot. The car gets hot in spurts. I have "burped" the system a few times between startup and cooldown. I'm always adding more so my gues is its not fully burped yet, however the car is getting HOT driving around. It will get within an 1/8" of an inch of the upper "operating temperature area" but it never goes between teh upper area and the red mark. Sitting in traffic the temp wants to go up quite a bit, but driving it teh temp goes down a bit. I've been having to limp it around with the heater on full blast to pull some heat off the engine. Just keep burping it or what?

Lastly, this is an automatic car, and it wouldnt go into 4th gear for some reason. I suppose i'll have to dig through the service manual for that, but anyone have any suggestions?

 

For the all of a sudden richness, check the map sensor hose. If it comes off or leaks a lot, it does this to prevent you going on boost.

 

Would the richness trigger teh knock sensor however?

And.......is this the "boost sensor" thats mounted on the firewall?
