ok short story...Last night I was fabing up my downpipe in my storage unit which is 1 1/2mile away and decided to call it quits after 4-5 hrs. It was cold and I wanted to go home and eat. put everything back together except my cat to header. Drove home with open header...kool sound right.

this morning I was going back to my storage unit to reattach my cat to header and my car died on my WTF!!!!! coasted over to a parking look and trouble shooted everything. Noticed that 1 of the 3 DC Header bolts where gone. Looked at all the spark plugs and they where pretty black. Cleaned them with a wizzer, sprayed them down with carb,brake cleaner and put them back in. While the plugs where out I rotated the crank to see if anything was binding and everything seemed good.

heres my problem....the car starts but wont stay running. It will start and idle at about 1 grand for 2-3 seconds tops and shut off. Then you have the cycle of the poping and backfiring and then it cranks again. I was ******* with it for about a 1 1/2 and still nothing.

Does anyone have any ideas. I know it could be:

1)bent valve
2)something electrical
3)I dont know

I have a obd0 b16 with DC headers,intake and stock exhaust. Also have gsr cams. I chipped it with BRE but everything has been straight since everything was installed.

When I drove it the only thing that I may have done wrong was not let it warm up b/c I didnt want to work on a hot exhaust. But that was it.

any comments. Anything said would be greatly appreciated. I would hate to remove the head if I didnt have to but want that to be the last resort.

Thanx

 

Are you trying to start it with the exhaust on or off?

I don't see how that could have damaged anything unless it's really cold out.

 

it was see you breath cold and I didnt let the car warm up but I thought the same thing. The exhaust is still disconnected. Im going to grab my jack after work and re-attacheh the exhaust and try it then. But this morning it started 1st try.

we will see I guess.

 

re-attached the exhaust and still nothing. I got it running for like 20 seconds and all I heard was bbbllllddllllllll....Got to be a valve. Im taking the head off tonight.

 

Good luck.

 

Im going to get new NGK's tomm. Try that 1st.

 

Check that your cam timing didn't jump. MFR priming the pump? Coil failure? What makes you think its a valve? What does bbbllldddllllll sound like?

 

the screw for the rotor button came out. lol.

thanx everyone. The plugs where fouled out, I was getting air so I dug into the ignition system and found it. I did a compression test and everything was good.
