glowing exhaust and the popcorn effect

[Bahdra]

ok I am about tired of the whole fix one thing and another issue pops up

kay my prop now is i put a cat in my car to pass emissions and when i fired her up it would hit pressure and just pop then if i lean on it it would hit 1 bar and rev out but Every time it would sputter hard
kay so i pulled the whole fmic off checked all the pipes and couplers washed everthing and put a coat of silicone in all the boots put it all back together still sputtered and the i was wondering what that the plastic on fire smell was looked up theres smoke coming out the back side so i check and my bumper is melted up and the exhaust is glowing orange not the whole thing but the cat and joints ...:faint:


omg somebody help
oh water level was little low and oil is at operating range

You are running rich and the cat is trying to burn off all the excess fuel.

[Bahdra]

kay well the things that make it run rich are boost leaks water temp sensors and what else? i replace the teh temp sensor and have checked and double checked the intercooler pipes

If your manifold is glowing it's timing.
If your cat is glowing it's fuel.

How are you tuned?

[Bahdra]

stock 65 ecu i have 2 spares all three run exactly the same tdc timing
mods are fmic, hks ver.2 bov, rebuilt t25 hybrid (not sure on specs but pulled harder than normal) with 1bar actuator, 3" down pipe back

kay the cat is glowing and it sputters starts sputtering at 0 psi but will rev to 1 bar after a second or 2 of sputtering

[!Zar!]

Is your cat clogged?

[Bahdra]

cat is not clogged im looking at it right now i took it out after it cooled down to check for damages
