HI guys as you all know my engine is up and running. anyways it starts up fine keep in mind i also installed a catless 3 inch downpipe i dont know if this has something to do with it? but anyways it will run fine at about 900rpms then into about a minute or 2 it will have this random out of the blue stall. but it wont die it just seems like its about to then it kicks it back up and then its fine??? what the hell is this???? i do NOT have my rear 02 sensor anymore i just disconnected it from the connector and showed it in the heat shield. this can only set a 02 code right? it cant make it do this crazy random drop in idle right? thanks.

nope... the rear o2 is only there to monitor the cat... it wont have any affect on performance.

thats what i though ha thanks but what the hell is causing it to RANDOMLY out of the blue cutout then revive its self a second later at random?

sounds like something else is wrong, not the downpipe doing it.

**GTPJOE90** · 10-30-2009

i think vacum leak?

it seems like the TPS sensor or something its very odd...... today after getting up to like 40 and as i was coming to a stop it was "acted like it was still trying to accelerate and all i had to do when stopped was take my foot off of the pedal and it was lanching??? wtf i agree lol

The scanner at Autozone which is a code reader won't tell you **** other than SES light stuff. Get a REAL scanner, for example..... Aeroforce Gauge, Scanmaster, Powertuner, HP Tuner, ETC... Not some ****ty autoparts store code reader... You should be modding without one honestly...

**GTPJOE90** · 10-30-2009

again....... poor college kid.... lol

Are you not going to school for automotive? If your school does not have a single scan tool you are wasting your money going there.

**GTPJOE90** · 10-31-2009
