So last night my car would not turn over. It sounded like it was not firing. But my friend ended up firing it up and it was good till earlier this afternoon when it WOULD NOT give. So we went and got some spark plugs, took out the crappy ones (which the front pair had oil on them). We then installed the new ones and the good news is that it started up the easiest its ever started up, the bad news is, it sounds like one or a couple of them are not firing. We also poured some SeaFoam stuff in the engine and some in the gas tank, it definetly cleaned up everything. After all the smoke cleared it was still firing bad, so bad that it was rich enough to shoot fire out of my exhaust with a cat. So I am wondering what could the problem be? I am almost positive that we installed them right, but since its not firing right, I have to second guess myself. So what should I do? And what is with the oil in the engine?

also, i took off the elbow to get to them because i had to come from the top and there was no gasket. Now I have heard that there is one, so what is the answer?

anytime there is metal meeting metal in a car, there is always a gasket because you will never get a good seal.

sounds like your engine is seized. what is your oil level?

There is no gasket for the elbow to throttle body mating surface.

FD'up, you should have an o-ring for that connection, however since its on the other side of the throttle body its not a vacuum leak.

FD'up

oil level is awesome, couldnt it just be the plugs. it turns on, its just the idle is crap it bobbles from 500 then pops up to 1000 then back to 500 so on and so forth.

FD'up

alright so i just tried to fire it up again and it did the same thing as night, what the hell!!!!!!

FD'up

has anyone else had this problem?

sounds like ignition or fuel then if you have lumpy idle like that. start trouble shooting dude. is your fuel filter good? how is your intake filter too? are your injectors shot? are your ignition wires in the right places? are you using the right spark plugs...?

FD'up

they are the right spark plugs and the wires are in the correct way. I dont know how to test the injectors, but it sounds like the pump is turning on and when some fuel does light, it back fires pretty big cause of the extra fuel, so i am pretty sure the injectors are fine. the only thing I am unable to check is the fuel filter, how do I do that?

Take it one step at a time:

* Make sure you didn't knock the MAP sensor vacuum line off
* Make sure you have the gaskets in place for the UIM (one from the LIM -> UIM, and then one from the UIM -> TB)
* Pull the ECU codes to see if you have any codes which might be stored but not making the light come on

and not to reiterate, but make really sure your plug wires are connected to the right plugs and you have a good connection at each plug.

FD'up

alright so i took out the new spark plugs and decided to get new ones since I only bought them yesterday. When I took them out, I noticed a lot of oil(and gas fumes). So I was wondering how much oil should be in the housings? if any? and I was also wondering how to check the coils. I dont know what else it could be because I put in the new spark plugs and it didnt turn over.

Primary injector stuck open? Are the plugs in both rotors equally fouled?

FD'up

i dont think they are stuck open. They only smelled of gas because I tried to turn it on 5-10 times. The rotors would turn, they just wouldnt light. and they are brand new plugs

Gadd

Have you tried any of these? Map sensor vacuum line, or check for codes? If you have and there is no problem there, check for spark, get a compression check.

FD'up

I know the all the lines are fine and so are the gaskets. I dont know how to pull the ECU codes. I have a power FC, how do I pull the codes? Also, how much oil should there be in the rotor housing? if any?

FD'up

I forgot- I also watched the spark plug reading on my commander and when I tried to start the car, it rea the the leading was getting 9 and the trailing wasa getting 5. I think they read it in degrees.

FD'up

any one else have any ideas- I was also wondering how to test the coils?

what labor needs to be done to get to the coils?

FD'up

So my car hasnt been starting up and I am under the assumption that it is my coils. I am going to Lows to buy an ohmmeter today just to check which ones are bad. And once I figure that out, I am going to go buy some of whatever needs replacing. So I was wondering what type I should get. I searched and found out that some people like the FC ones but they require some customization. Should I go back to stock or get an after marker one?

Also, I was wondering if you can test the coils through the wires instead of having to take off the UIM and so on and so forth. IF you guys can help out at all, I really need it. I am down here at school and that is my only means of transportation.

i doubt it is your coils.

coils generally start malfunctioning under heavy load rather than the light load of starting. the first thing, besides checking for spark and fuel is to change plugs which def can be the cause of not starting. if you are low on funds just change the lower 2 plugs as they do all the work.

keep us posted and good luck,

its not the plugs, i have already changed them out twice. The first time I changed them, it started up with crappy idle and I was shooting flames out flames with my CAT. This tells me that I am not fireing fuel. After I turned it off and then tried to turn it back on a couple hours later, it didnt turn. When I turn the key, the rotors would turn and you could hear it sputter out the exhaust, but the fuel would not light. That is why I am going to check the coils, also because coils can just GO bad without warning.
