Bad coil?

[thepowderblue]

well My car kept dieing when I stop so I made this thread >http://cb7tuner.com/vbb/showthread.php?t=177328.
It was not alot of help.
Here is a list of all of the stuff I replaced and or did trying to fix it.
Fuel pump is new.
ngk plugs
wires
cleaned the cap and rotor
replaced the fuel pressure regulator
Replaces the iacv & gasket
egr valve& gasket
Air filter
fuel filter
igniter inside the distributer
main relay
cleaned and replaced some of the wires in the distributer
and the list go's on.
It it getting worse now. I use to be able to stop it form dieing now it just dose and alot more then it use to. Its so bad I cant drive it around the block, Now its super hard to start. It has a bad misfire but only under load at 1500 rpm's. So I can rev it to 1500 it N or P and it acts fine but when I put in in gear then It misfires... I went and got a new coil off ebay and it wont be here for a week. What do you guys think will the coil fix it or what else could it be?

tighten down your fitv and then adjust idle and reset ecu. I had the same problem after fixing everything on the intake manifold the problem didn't go away until i reset my idle the proper way and my car idled fine beforehand. It can't hurt anyway it's free.

Adjust your idle. Lot of experienced guys on here you should listen, and not re-post saying you never received a lot of help. You can also try searching. Turns up a lot regarding Idle. Reading doesn't hurt.

My idle has nothing to do with it. It will die when I am on the gas.It never use to but it will now,And I replaced my iacv
And I do listen and I did most of the stuff they told me.

When car stalling is not gradually become frequent over time and also occurred not only during cold wet weather, the only possible problem of the car is a bad throttle position. Fuel injected engines have a throttle position sensor, a device which measures how far a driver pressed the gas pedal and thus the throttle. The position sensor feeds the data to the engine computer that does the calculation the resulting data is used to determine precisely how much gas the fuel injection system should inject into the engine. If the throttle position sensor provides a wrong data to the engine computer it will adversely affect the injection of gas into the engine causing the car to stall when accelerating.

Few articles on here about TPS.

I Has my brother check my tps with a multimeter and he said its good. O I thot I should add that I checked my fuel pressure at the rail and it's at 30 psi at idle.Is that good for a ebay fuel pump?

Man, I'm inclined to believe it has to be an electrical issue. I would suggest if you have a friend with an ECU to swap them temporarily to see if that will solve your problem.

will I have to use a ECU out of an SE?

so what do you think about it being the coil? It sounds electrical to me also. A mechanic that lives a few streets over thinks its the coil to. Its not like the car just shuts off its like its being starved of spark.Its like the coil is on its way out so It needs more juce to work and it can only get it reved up and when I go to stop the alternator stops making all of the power because the rpms drop and it It cant get that extra power it needs so it dies. It dies alot easyer when I have the A/C on or the headlights. When I am driving my alternator gives off like 13.5v and and idle it makes 12v.
Does it sound like that to you?Any other theory's?

[CBsaurus7]

I would test to see if its your coil. Also, make sure you test your pick-up coil as well. And you would have to use an EX ECU, unless someone knows otherwise.

I know the 90-91 ex does not have abs and its ecu is tuned for the f22a4. The 92-93 ex has abs and the f22a6 like my SE, How Will I test my coil? I know its at least some what working.whats the pick-up coil? Is it that thing that I called a igniter? If Its that thing I changed it. Is it inside the distributer? As far as I know our dizzys have 3 cps sensors, an igniter and the 90-91' have a coil,

any ecu for any trim cb will work. but i agree it has to be electrical.

Doesn't the ecu control abs? so wont I have to get one made for a car with abs?I know If I dont get the a6 ecu I will loose a few hp.

I thot I might add I friend noted that it smelled like my car was running rich.

[thepowderblue]

so I think I fryed the coil because the spark is super weak and one day I took the cap off and I lost the spring and I put the cap back on not knowing that I lost it. Could that fry it?

[YK86]

Are you talking about the spring that pushes the center pin out on the distributor cap? If so, then yes, you could have damaged something as no spring will probably cause arcing as the center pin isn't contacting the rotor like it should.

FYI, the ECU does not control the ABS. There is a separate ABS ecu for that.

ABS is a separate computer in the trunk. The ecu only has to do with the engine and a little bit with the trans.

My mom thinks my cat is gone until my car warms up. She always thinks it's leaking.

I didn't know there was a spring in there....
