Hi I just got done installing a new head gasket on my 86 951, the car ran fine before but now It doesn't want to start, I got it started twice and both times it was running very poor and puking huge clouds of black smoke out the back , if i get the rpms up to around 4000rpms it seems to run ok just at that speed only but still does smoke a bit and if I go any higher it runs bad again and loses power.
at the moment the car will not start, spark is good, did a compression test and got 130,130,110,120, which I think is basically ok?
I can crank it and crank it and it will not start but then if I unplug all the injectors and crank it after trying to crank it with the injectors plugged in it will fire up for a second till it burns out the gas in the cylinders and then dies again.
I even tried disconnecting the AFM from the intake boot so that it would see no vacuume and give max lean setting, but it still floods out during startup.
I disconnected the throttle position sensor and the O2 sensor and still flooding?!?! even unplugged the AFM sensor wires with no change .....the only thing I can think of at this point is that there is something wrong with the DME ....I have some performance chips in it by the way, forget the brand offhand, I think it starts with an M ?
