Contour Enthusiasts Group Archives Forums Modifications Duratec Maintenance Question about fuel injector sizes/colors....

OK, well I got another call from my step father about the car, but now my mechanic thinks that my CEL codes are due to the injectors. He thinks that they are the wrong size for the car. Supposedly they are orange or something, my question is, is there a certain color that the injectors are supposed to be and/or does anyone know what size orange would indicate? By the way the car is a 98 CSVT.

I know its kinda vague, but thats all I have to work with and my stepfather is the middle man and he doesn't know much about cars.

Thanks guys

That would be kinda weird if it had the wrong injectors in it. I think the SVT's are 19 lb. and the non-svt are 17 lb.

I'm pretty sure the SVT injecors are orange-top.

Can you get the codes?? If you get the code and search for the code in either the troubleshooting section or the Duratec maintenance section, you will find quite a bit about what the problem really is.

If they can't give you the codes, Autozone will read them for free. Be sure to write down the number, along with the description of the code (if they give you one).

Trust me, I am well beyond the codes right now. The two codes are P0172 and P0175 which just say both banks are rich. The MAF has already been replaced, the o2 sensors were all monitored and are putting out the correct voltages, replaced PCV and all that good stuff. I wouldn't think that the injectors were messed with I am just going by what the mechanic told me.

I am at a total loss as to what the problem is with this stupid thing.

Your MAF was likely fine. Dirty MAF wires usually throw a lean code.

If you're not running a stock air filter, put one in & see if that helps after 3 or 4 drive cycles.

When was the last time you did a TB cleaning? Couldn't hurt if it's been a while. Also check the voltage coming from the TPS. If the voltage readings from that are wacky, that could cause a problem.

You getting any hard start, smell of gas on cold start, or rough idle when warm problems? Those might indicate an injector or two stuck open. But both banks... That baffles me. What are the odds two injectors on opposite banks go belly up?

To answer some of your questions....it is still stock air filter so thats not an issue and as far as the MAF goes, when he tested the voltages from the MAF it wasn't reading high enough at WOT....it was only going to like 2 volts or so when it is supposed to be between 4 and 5. I haven't cleaned the TB at all because I just recently bought the vehicle and the light has been on since I bought it and I also haven't checked the TPS either. I can mention that to the mechanic tomorrow and see if he checked any of that yet.

I honestly don't think it is the injectors either, but we are running out of ideas.

Thanks for the input guys.

TB cleaning is a do it yourself project really.

If you prefer to have your mechanic do it, he should replace the TB gasket in the process & charge between $70 and $100 for the service. PepBoyz charges about $80 last I looked, but I won't let those psycho monkies with wrenches touch my cars any more.

Yea I know that TB cleaning is a do it yourself thing. Honestly I could do all of the work on it myself, but I was having trouble diagnosing it thats why I brought it to a mechanic that we are good friends with. He wouldn't charge me any labor on cleaning the throttle body if he were to do it anyway, so I may stop in today and mention a few more things to him to give him ideas.

Thanks again guys
