I posted this in the eg/ek forum but I think I need it here because nobody is helpin. Sorry if this is the wrong forum.

Well I thought you would look.
I have a 98 ek with a ls vtec swap b18 block w/b16 pistons 99stock b16 head 98 ex wiring harness, obd2-obd1 converter,p28 chipped.

the problem is that at first I had someone I met through urban-racer do the swap. The kid told me he knew what he was doing.

Well he put a b16 head gasket on the engine witch now I know that it need to be a ls head gasket. Before it wasn't popping vtec. Well short story short I fixed the head gasket.

When I drove it after it was installed everything seemed great. It was popping vtec first,second,and third gear. When the car was on third gear it started making a "back firing noise" really loud. The car shut off and started ******* up. I had my boys fix the car after the kid from urban racer. He knows what he is doing. My boy told me the engine is fine. He checked the compression and he said it was 230-235 on off.

The engine was making a weird noise and some smoke came out the Intake Mani. . The weird thing is when u let it sit for alittle bit the cars gets fine for about 5 mins. The only code its throwing is the o2 sensor. It is not connected but my friend said that cant be the problem. Well his his going to hook it up later when he gets a chance maybe tomorrow.
So my question did this ever happen to you? Or can the o2 censor be the problem. Please any input from people who have done this simple swap would help thank you.

 

Please any info, Did anybody ever expeirence this before?

 

check the ground by the thermostat housing, check the timing belt marks and get rid of the O2 code first.

 

someone please help. could it be the dizzy? its an 0bd1 blockw/an 0b2 head w/an 0b2to1 jumpper harness and the dizzys obd2.
