Idles rough and engine shuts off

[blitz43]

hello guys i have a serious problem


my car is having really bad time keeping idle
it throwing 14 different codes and its running pig rich

another thing is that the tps is running 100% and does not change
and water temp is -40 degress

i found that out with the data logger

also after you put trans in gear the engine shuts off
if you rev the engine and as the rpm drops it sounds like the engine died but catches up angain when the rpm is low

this started after i did new side mount install and when after the t-25 blew and was spewing coolant and oil out the exhuast

after i did the 14b install the car ran okay but was having really hard time getting up to speed and to spool the 14b

i don't if that would help answer why my engine cuts off

does anyone know whats up with my ride ?????
the dealer ship couldn't even find out what wrong with and gave it a diagnosis
it was a mazda dealership which is where i bought the car from


here are my current mods

95 gst auto


walbro 190
intake
14b turbo
1g bov
all free mods
hallman mbc

thats about it

please help me out here im stuck with a ride doesn't want to drive!!!!!!!

well, its really hard to tell with a problem like that without actually being there... first thing i would do is adjust the cam timing, and then the idle... try those and then see how things run and what it does next.

First off, it would probably be beneficial to find out the codes being thrown if you havent already, or list them here if you have. Autozone/Pep Boys will scan them for free for you. The first thing I would check would be boost leak, as this is a good idea anytime you have messed with the turbo/intercooler fittings, and I believe the O2 lost in the process would lead to the rich condition you're describing. This could also cause the poor performance and stalling.
Check this article for a good step by step.

Reread your post and saw the part about spewing coolant/oil out the exhaust. If any of the codes have to do with O2 sensors, it is very possible that they were fouled by the burnt oil. This would also cause A/F ratio problems, although I can't imagine it would be to the extent of your problem (the ECU simply runs off the base tables).

Good Luck

*sigh* I've answered this question three times today already and I've been online for 15 minutes.


1. Check boost/ vaccume leaks.
2. Is your BOV Open Atmosphere?
3. Check spark plugs/wires
4. Check your MAF Connections and your o2 sensors.

i don't vent cause i ain't a no0b
i have experience boost leak before and it aint it
plugs are good wires are good


the only left is to change the o2

You still haven't told us what the "14 codes" are.
Fix them. One at a time. Chances are you'll fix your problem by fixing them.
