S-Nation S13

some call it wasting ...some call it investment MR. ASE you out of all people should know cars will break,parts will fail!!! why fix one when they all work together as a whole

ok well if you here to stop mis-information than, like in true zilvia nature do a search...

"By simply performing its function, the knock sensor does two things for your vehicle's engine: (1) it allows optimum engine performance and (2) it protects the engine from potential damages caused by detonation. And because nearly all stock knock sensors used on vehicles today are dependable, you may not find a need to replace them for the life of your vehicle. Acts of carelessness, however, may cause the knock sensor to get damaged. Running the vehicle using fuel with much higher volatility or much lower octane ratings than what is recommended by the vehicle manufacturer are among those things that may cause knock sensor failure."

"Many factors can cause such detonations. Among them are too much carbon deposits on the cylinders, spark plugs that are too hot for the engine, high combustion chamber temperatures, and too advanced spark timing."

Many factors lol not can be related to the egr..but more than less its main funtion is to protect engine from detonation error due to timing issues

so if egr primary function is to do this.. its safe to say that egr/knock sensor failure more than less are 2 seprate part failures rather than part failure do to other parts...unless timing and basic engine function is an issue

DENNYDIZZO you want a fix well here it is...

s13 FSM states idle with no load is 700 +/- 50 rpm which puts you at a minimum of 650 rpm or a maximum of 750rpm ..not 850 rpm fix that first..
1.check timing 20 degree +/- 2 degree
2.idle speed 700 +/- 50 rpm

you can quote me on that "BLAZEDGLORY" aka MR. ASE

that means your egr valve works but the valve is controlled by EGR BPT VALVE the other UFO looking thing above your egr valve which is controlled by vac

its a used car, do you persoanlly know the previous owner?? driving habits?? did they to all the maintenence?? ...HIGHLY DOUBT IT but maybe you do


IM NOT ASE CERTIFIED I DONT HAVE A MASTER ..but what i do have is common sense and the knowlegde to fix problems, the knowledge that some ASE/MASTER techs lose cause there all hyped up cause they passed some test and got a flimsy @ss certificate..to be honest i know car guys that can fix cars better than are so called reliable auto-technicians and dont have certificates!!! blazedglory just to let you know auto-technology/engine perfomance was my major but i dont flaunt it !!!!

DO WORK BEFOR TRYING TO SAVE THE FORUM WITH MISINFORMATION when you yourself miss the key points. Read into the information given sometimes youll already know what to fix !!!
blazedglory you fail EPICALLY!!!!
