What does the wiring diagram look like to make sure everything is plugged into the right spots?

Where the wires are they should be a Diagram of 110 to 220 make sure you got the right wires on the right spot.

Thanks for choosing FixYa and welcome to the site. This is very well possible. If the plug wires are in the wrong spot, it will cause this. Make sure that the spark plugs were gapped correctly as well. Most plugs come pregapped but just make sure. Check for any wires or hoses that may be loose from changing the plugs. Make sure everything is put back on. When you change plug wires, make sure you mark them. I would double check the plug wires. If you didn't have this issue until you changed them, more then likely, that is whats wrong. If you have any questions, feel free to ask and thanks for using FixYa.

if your car fires up, then the spark plug wires and coil wires are properly done. if it is running rough then you may have made one of several mistakes.

you may have needed to "gap" the arc end of the spark plugs (unless they were specifically "pre-gapped" for your particular make and model).

you may have not tightened one of the spark plugs all the way in, allowing too much air to enter the combustion chamber.

worst of all, you may have cross-threaded a spark plug, which would also allow too much air into the compustion chamber. it is usually possibe to re-thread the spark plug hole, using what i believe is called a "tap-and-die", but i have never done this before, so i am not sure if its success rate or difficulty level.

Haynes repair manuals would have good wiring diagrams. Or google it, you can find about everything on the internet, but sometimes a problem with too small of print, or maybe my computer skills need sharpening.
I don't know about those wire connections not plugged in. Are you sure they are from the doors? Can't imagine what they would be.

i didnt fix it on my own couldnt get the diagram from you your site only gave me a ad for hp printers
i had to take it to a garage to take care of it i dont know if i hit the wrong link let me know

first verify plug wires you might have one crossed. get a wiring diagram and check each wire from the cap to the plug , cyl 1 to cyl1 ect. it is very easy to cross one. make sure the wires are on the cap correctly, make sure the cap is on correctly. any part store will give you a tune up print out showing cyl location plug wire timing ect. then you want to check everything is plugged in from vacuum lines to tps to mass air to map sensors . the car ran fine before this so its simple just retrace and look closely i bet there is 2 plug wires crossed or something is unplugged. just do one wire at a time from the cap to cyl. make sure your going the right way on cap. just get the tune up print out and retrace each wire.

I would like to see a plug for a aiwa car stereo

well you have several options you can go to a dealship and have them copy the diagram for you(i do this all the time) or you can purchase a repair manual at Napa or Oreilly's for around 20 bucks. it has diagrams and schematics in it. it also has alot of instructions in it so you can do repairs yourself. By the way i'm surprised that the mechanic doesn't have these diagrams himself. I was wandering why it won't start after you changed the plugs and wires could it be that maybe the firing order is wrong. i've done that myself a time or 2. double check the the plug wires to make sure they are in the right spot. if the problem is it won't crank. chances are you have a loose ground. please rate this..thanks

If it started when you changed everything, make sure the cap is tight, plugs are gapped correctly, wires are in right spot.

Good Day,

You didn't specify your engine size so here's a few diagrams:

2.0L 4cyl

3.0L 6cyl
3.1L 6cyl
3.3L 6cyl

I have labeled these according to engine size, make sure you use the right one.

Good Luck and hope this helps
