tore the whole thing down, everything except for the turbo manifold came off. Now heres what happens. I can get it to start and idle on its own now, so i took it for a drive. Drove it around the block. Car drives fine in vaccume, but if you hit 0 vaccume it bogs and exhaust pops a ton, like its dumping a ton of fuel or something. Anyone know why this could be. Couple things i need to fix are the water temp sensor is not working, and im not running a 02 sensor right now. Can these effect the stock ecu from keeping the car running? Nick i WILL be giving you a call.

Fix the water temp and the o2 sensor.
Check the boost sensor to see if its within spec. |

tried clearing the ecu, no luck. I have two cars for sale, 89 TII 40k orig miles on car, orig blaze red paint, mint black interior, 1700 on a streetported motor, lots of other mods. Just needs the kinks worked out. I have not the time nor the money to be doing this. I have no dd, and cannot afford one unless I sell this. Also have a 93 FD for sale. Silver, 38k original miles on the car, tons of mods, motor is blown. Has compression in rear rotor, but no seals left in the front. Car is mint inside and out, also has a $2k eclipse stereo system. PM if you have questions about them.

doesnt throw a code, thats the weird part. The previous owner of the engine could not get it to run right on a stock ecu, he said it would feel like it was running completely out of fuel as soon as he hit boost, which is the same thing as me. Maybe the porting was too much of a change for the stock ecu to work with? He said the problem went away the second he put a haltech on it. Im going to disassemble down to the short block, get all new gaskets, and reassemble everything. Im going to check the AFM, TPS, and MAP sensor/pressure sensor. If i cant get it to run right Im just going to put in a E6k over the winter and keep it. I just cant part with it, im going to cry when the FD drives away on the truck to its new owner. I just cant let myself get rid of 2 under 40k mile RX-7's in one month...

I had a similar problem and it ended up being the afm

see if it stays running if you keep your foot on the gas
sorry for the double post |
