Ok, I have a 92 SC300 with 177k miles on it. Right now I have done a full tune up, cleaned out the fuel system, put a custom intake on it and flush and filled the tranny. I have 2 engine codes, 27 and 71, and not sure what either are. I believe 71 is EGR and I have already gotten rid of it once but it has come back. 27 code I am not sure of still. Also, when I floor the gas pedal, I get terrible response when the tires should burn some rubber or at least squeek. Once it hits about 2400 rpm it takes off. I know this is quite a bit of info, but please somebody help me. No one has answered any of my previous threads and its really started to suck. Now along with all of this, I also get pretty terrible gas mileage (already put new O2 sensors in) and it sounds like my fuel pump never shuts off once it reaches pressurization. Again, if anyone can help, please let me know some things I can do to start narrowing down these problems.
