Hello everyone.
right now i am frustrated and don't know why i bought a RX-7 in the first place (trust me, i'll love em again when i fix this problem) but what i did was this

Yesturday i've changed my spark plugs, since my upgraded turbo and such from reading on this forum, i've changed to BURP9EQ on all fours instead of 7s on leading and 9s on trailings

well after that, i took out my belts and installed the dual pulley.

first thing, the car is harder to start (i think it is due to the 9s leading plugs) but yesturday, when i tried to start it, i thougt it was flooded. so I started the car, with foot down, no luck.
I started with foot not on gas, no luck. then after cranking it a few times i hear a loud POP. so confused and afraid, i thought it was my exhaust backfiring, but since i have a cat installd i thought it blew my cat....

well, after dinner, i tried again, and it started... but after driving it whenever my boost is at zero bars or near it it bogs like hell.... I've looked for vac leaks and such, all I have not looked at is the exhaust pipes and 2 IC pipes connecting the turbo and the IC.

It seems like this is caused by a vac leak, not major enough to make the car unstartable, but enough to make it bog at 0 psi.

Also just making sure, the spark plug wires, is T2 the rotar NEAR the radiator T1 near firewall or is T2 near the firewall and T1 near radiator? (right now i have T2 and L2 near radiator, T1 and L1 near firewall)

what can be causing my bogging? please help... what was that POP when i started my car?

I am so stuck right now

thanks
Jonathan

 

Doesn't matter where the spark plugs are as long as you have trailing on the top (T=trailing... I just say it = top) and L on the bottom (leading).

For the sake of it... Compression test?

 

Bob means double check that your ignition wires are in the correct spots, if they are backwards (leading in the trailing position and vice versa) it can cause some wierd problems.

 

it was running fine 2 hours before the POP


just read from other posts, T1 is the front rotor T2 is the back, L1 is front L2 is back...

ok that makes sense and mine is wrong right now, but will that make the 0 psi bog?

 

may as well put them in the right spot and find out.

 

well i'll look into that (wish i had a garage, but its pitch black outside.. =)
anyways one more question, anyone running all 9s around? with any idle/starting problems?

 

ok update:

IT IS THE DAMN FIRING ORDER!!! been stressing all day....

thanks guys, the car runs great now
