2.3s MissFire & CEL blink

[pawns17@yahoo.com]

I just put in new spark plugs re tightened my valve cover gaskets for the back and front, re-did my vacumm lines ( some lines were longer then default ) & t's ( some t's are diffrent then default) and all of a sudden wen I turn her on she idles a little rough and wen I put her on drive she wont acell much and feels extra weak. My cel light is blinking as well. What else should I do?

I am guessing that you had no CEL illuminated prior to your plug change?? Did you put in NGK stk #(3741) laser plat plugs or something else?

I did have the cell light on before now she blinks, and no I used the pzrf5-11 instead and gapped them to .8. I understand that you are not suppose to regap them since they are lazer plat and you can mess up the center. Although this is true the car shouldn't be this weak. I cant get the code at this moment because she is barely derivable, I can't get her to autozone. I will like some tips I can try before i choose to drag her all the way to autozone then back again?

I am continually learning a bunch from the other more experienced folks on here. It looks to me that you have the wrong plugs installed if you have a 2.3 S model. Only the 2.5 engine can take the -11 plugs that you installed. That would appear to be the reason for your multiple misfire condition at present. I am sure others will more than likely concur.

I understand that the plugs are not for the 2.3l. Like I said I re-gap them to .032, and it feels extremely weak. What else should I take a look at besides the spark plugs or do you feel this is whats causing all this weird bucking and low power accel?

And thats where the problem is. You're not suppose to re-gap plugs for the 2.3. The OE plugs (NGK [3741]) plugs are the correct kind. I think the true gap for the 2.3 is like .028-.031" iirc. milleniatech.net - Spark Plug Information VERY GOOD WEBSITE IMO!!!! The NGK's PZFR5F (3741) says .032" on the box but they are original equipment. I've never understood that little difference in detail though. NEVER RE-GAP plugs for this tempermental motor.

Ugh I really do hope that thats is the problem. If that doesn't work :|

ok the sparks did not fix the problem im getting all cylinder miss fires and also o2 censors. also i re tight the valve covers and i am beginning to think that wen i took the bov inter coolers i may have to take it all back of and put gasket paste on the supercharger, i think is pulling air and causing all that bucking. i re checked the vacuums i am going to do it one more time wen i get under the abv-cooler and see if that fixes the bucking problem.

when checking the vac lines, make sure you didn't reverse any of the 1 way check valves either. that can mess up stuff too

there are 2 (green/white) valves in line with the vacuum lines

note there are also 2 hoses (on the brake booster line) that have check valves inside the actual tube. one attached to the ABV vent which should have the yellow arrow pointing to the ABV, and the second on the left side near the belts. the pipe running under the left intercooler pipe near the serpentine belts should flow only towards the vacuum pump.

I checked that as well I am begging to think that I need to re seal the gasket from the superchager to the abv that sits on it. Also re seal all inter cooler gaskets as well I am not getting just one cylinder miss fire but all at once so I am begging to think is leaking air or it isn't compressed right.
