Noahkk19 Posted May 16, 2006 Author Report Share Posted May 16, 2006 yeah vacuum, thanks for the clarification...sadly that is the very least of my problems. When I pulled the spark plugs and saw the condition of the plug for cylinder 3, it looked like straight stuff...and with the ECU doing its job I sure enough have a misfire code for cylinder 3. If I've checked every single last component...every single one, what could possibly be wrong? $5 paypal to the person who diagnoses the problem correctly I'm thinking fuel injector? Someone throw some reasoning in here!! PLEAASE Link to comment Share on other sites More sharing options...
Chris_R Posted May 16, 2006 Report Share Posted May 16, 2006 Clean the spark plugs, flip-flop the injectors and see what happens... It could also be the injector wiring. Link to comment Share on other sites More sharing options...
connorb850 Posted May 16, 2006 Report Share Posted May 16, 2006 I'm thinking fuel injector? Someone throw some reasoning in here!! PLEAASEIts possible. With the car running at idle, try unplugging each injector one by one. If the injector is working properly, the car should run worse when each one is unplugged. If it runs the same, something is wrong with the injector you just unplugged. Link to comment Share on other sites More sharing options...
Noahkk19 Posted May 17, 2006 Author Report Share Posted May 17, 2006 The Haynes manual tells me I need to depressurize the fuel system...With what you just told me I'm guessing it's more than fine to leave everything alone and just take off the fuel rail and work with the injectors while everything else is connected and fuel pressurized on the car?

Noahkk19 Posted May 17, 2006 Author Report Share Posted May 17, 2006 Just noticed that the car needs fuel to run on idle Me=Not Smart B) Link to comment Share on other sites More sharing options...
Noahkk19 Posted May 17, 2006 Author Report Share Posted May 17, 2006 Checked the fuel injectors switched the #3 injector with the #1 injector and still got cylinder 3 misfire codes...I've taken every route, any last suggestions before it goes to the shop? Please :) Link to comment Share on other sites More sharing options...
ziddey Posted May 17, 2006 Report Share Posted May 17, 2006 Ok, so to sum up, the following have been done already and problem is still there:plugs, cap, rotor, wires, injectorsYou said you found a stray vacuum hose. Have you figured out where that goes?Any way for you to do a compression test? Is it still idling poorly?Maybe some sick sludge of something?Would it be possible that it's the camshaft position sensor? I pulled that out of my asshole though so someone better than me can chime in on the ludicrousity of that Link to comment Share on other sites More sharing options...

I pulled that out of my asshole though so someone better than me can chime in on the ludicrousity of thatI'm thinking the vacuum hose that I found is irrelevant and was left there from previous work because I found it under the battery...Sludge is a possibility...The only way I can get a compression test done is if/when I take it to the shop...Still idling poorly...and yes there is a vacuum leak somewhere still prevelant, but where are my codes at? Should I risk driving the car slowly around and seeing if I get any more codes? Everytime I reset the codes and start the car I don't let it run for more than about 3 minutes and the car just idles, I haven't driven it one bit Link to comment Share on other sites More sharing options...
ziddey Posted May 17, 2006 Report Share Posted May 17, 2006 hmm if it's just a misfire it isn't that bad. that vacuum line sounds like it could be your cruise control vacuum line. Does your cruise not work? If so, I'd ignore that hose for nowWhat color is the smoke that's coming out the exhaust? What happens when you rev it? Did you get water into the cylinders? Are the plugs screwed all the way in? You didn't use loctite or anything on the plugs right?I can't remember if anyone mentioned but our cars don't like platinum plugs. Coppers are the way to go. But it shouldn't have as big as deal as what's going on.You said the wires are in good shape. Do you have an ohmmeter to test the wires? Link to comment Share on other sites More sharing options...
Noahkk19 Posted May 17, 2006 Author Report Share Posted May 17, 2006 I have intermittent blue smoke, I know the turbo has been on its way out...I do have to check the oil often because it is leaking from there...No water in the cylinders...Plugs were torqued and are gapped correctly and nothing was used on them...Yeah I was made aware that copper is the way to go after I got the platinums but like you said that shouldn't be causing a problem especially when they're brand new...And no I don't have an ohmeter to test the wires...The reason I am not blaming it on the wires is because of the fact that I switched them out for the ones on my 850 Turbo and the same thing happened...The cruise control has been working lately by the way...Could the leaking oil I have from the turbo cause some problems? And also the cat...That is a possible culprit but once again why am I only getting a code for cylinder 3 why not 1,2,3,4 and 5? Link to comment Share on other sites More sharing options...

Can you take out the spark plug and look at it one more time just to be sure? Have you ever starved the engine of oil? I haven't ever had problems with cyl3 but I have with 5 lots of times because of a poor tool used to take out the spark plug and I end up cracking the ceramic often !

Noahkk19 Posted May 17, 2006 Author Report Share Posted May 17, 2006 It was starved once like 4 months ago...Ever since I got even more obsessive with oil checks than I already was...And I will go ahead and check the spark plug one more time just for the hell of it...

ziddey Posted May 17, 2006 Report Share Posted May 17, 2006 Sorry about having to check it over. I know how much of a pain it is to go back and redo everything again. If it's not empty on oil right now, and everything checks out fine, then I don't know. I might consider giving it a hard run and see what happens. You wouldn't happen to be in an autorx treatment at the time would you? I can't make the guarantee that someone won't blow up but it shouldn't from what you're saying. A very severe vacuum leak could cause intense stumbling that resembles misfiring, but because you're getting codes, that's probably because there's actually a misfire. Maybe the code didn't clear out correctly? Link to comment Share on other sites More sharing options...
Noahkk19 Posted May 17, 2006 Author Report Share Posted May 17, 2006 Everytime I've cleared the codes it comes right back, I think a 15 minute drive is in order but I'm just so scared of causing damage to the car...On the other hand I feel like a little longer drive may reveal more codes possiblyAnd for some reason I'm thinking oil is a possible culprit Link to comment Share on other sites More sharing options...
connorb850 Posted May 17, 2006 Report Share Posted May 17, 2006 Are you sure that plug is oil fouled? Its possible all this stopping and starting the engine from you checking things has fouled the plug with gas. Give it a good run and then recheck the plug for cylinder #3.
