my sc400 is throwing 8 codes =( help me fix PLEASE!
Well I just checked my diagnostic box because my car is having a starting problem about every 2 weeks or so. And come to find out I am throwing way more codes than just the one I thought it was....
12- RPM signal
24- IAT Sensor Signal
25- A/F Ratio Lean Malfunction
26- A/F Ratio Rich Malfunction
52- KS Signal
55- KS Signal
71- EGR System Malfunction
78- Fuel Pump Control
I just bought this car about 2-3months ago and I don't know much about them what all do I need to get ALLLL those fixed??
Thanks in Advance to anyone knowledgeable about this.

This is what I have come up
-Clean my mafs - but with what?
-buy two new distributors
-maybe new knock sensors to fix the Air Fuel readings BUT first go and buy some spark plugs and seafoam my car before i spend $300 on Knock sensors
-new egr position sensor
I dont know what to do about the fuel pump code though?
also correct me if i am wrong please

So all that may not be wrong and its a computer problem?
for some reason that sounds hard to believe but i have no idea... i shouldve stayed with my s13 that i know up and down left and right
RIGHT NOW my car is doing these things:
-rpm and mph gauges dont always start working until i drive for like 10-15mins than they come on randomly and stay until i turn the car off and back on. sometimes they come on and stay on from the get go or 1 at a time.... TALKING ABOUT ACTUALLY READINGS NOT LIGHTS
-lately i have to left my car get fuel by leaving my car in the on position without starting it so fuel pumps or it wont start up right away (i bypassed the fuel pump ecu) COULD MY BYPASSING THE ECU THROW MOST OF THESE FUEL CODES??? I didnt splice the wire and plug the plug back in a just pinned the two wires through the plug.
-it is laggy from around 0-25mph, BUT sometimes just flies right up there....
hmm thats about all the problems i am having...
