Hey guys, my name is Patrick. I bought my first rotary in February, 88 s4 Gxl. bought it with a cooling issue, swapped rad, no issue. Fixed. Now I don't know what to do. My car hits a wall anywhere between 2k-6k. It's really strange. It's intermittently occurring. It's like it's choking out or not getting enough fuel. The weird part is, is that it's only at full throttle. If I ease off the throttle, it's will sometimes accelerate, just slowly. I know my 5th and 6th ports aren't working, but maybe fuel regulator, injectors, maf? Idk. Stumped. Any help would be great! It's my daily( if she wants to work), so I can't keep taking things apart...

 

I'd try fixing the ports first..

 

The thing is, the ports weren't working when I bought the car, and this problem just recently started.

 

This prob is intermittently occurring. Any ideas??

 

fuel filter maybe

 

Swapped that, and the fuel pump.

 

what is the cooling issue you speak of?Is it eating coolant?

 

No issue anymore, it had one. When I swapped the radiator, it fixed it.

 

I'm thinking the ecu ground under my uim will be culprit. Can't get into that right now, will prob have to wait. I'll fix the ports while I'm in there too.

 

don't forget the O rings in between the lower manifold and the keg when ordering parts.

 

Got em

 

The ground was corroded.. Stripped the wire, and reconnected it. Got the ports working. What else should I check tomorrow morning?

 

Okay.. Got the throttle body off to look at, and the thermowax pipes were terrible.. Explaining my high idle. 1 pipe was rusted and clogged, the other clogged, corroded, and broken. Bad.. But I reconnected everything and cleaned the thermowax to what I could. It didn't want to start at first, but got it running, and drove it. It was doing good, and redlined it. Then I got it fully warmed up... There is a belt squeaking at anything over 5k... And the problem came back... Great. Back to square one.

 

Did you get the injectors rebuilt or cleaned. Also make sure the pressure sensor is good. I had a similar issue withy tii but between 5&6k

 

Well... Ended up wrecked and totaling the car.. So thanks guys, but no more fc for right now.. :/

 

R.I.P. Poor FC

 

At least you are ok? R you going to stay in the rotary world?

 

Yeah. And I'm torn. Dunno yet

 

Actually.. Looking at some rx7s
