Poor Throtle Response
I HAVE A 302 INJECTED 70MM THROTLE BODY COBRA UPPER AND LOWER INTAKE, FULL MSD DIGITAL 6 PLUS IGNITION, RUNNING 6 PONDS OF BOOST WITH A NEW PROCHARGER NON INTERCOOLED SELF CONTAINED UNIT (MEANING NO OIL LINE TO THE OIL PAN). MY THROTLE RESPONSE REALLY SUCKS RIGHT NOW. WONDERING WHAT IT COULD BE AND HOW MANY THINGS IT COULD BE. I ALSO NOTICED JUST YESTERDAY WHILE LOOKING AROUND UNDER THE HOOD THAT I HAD OIL IN THE LINE THAT GOES FROM MY UPPER INTAKE TO MY BOOST GAUGE. :confused: THE CAR ALSO RUNS LIKE IT HAS A BIG ASS CAM IN IT SOME TIMES, MAINLY WHEN I PUSH IN THE CLUTCH. WHEN THIS HAPPENS I CAN SEE MY VOLTS GO UP AND DOWN AS WELL AS MY BOOST GAUGE. THIS HAPPENS NORMALLY AT IDLE:mad:
ANY INPUT FROM ANYONE WOULD HELP, BIGBOOTHE |
Absolute guess:
volts and boost going up and down, they are both driven by a belt, maybe the belt is slipping. |
Hi,
I ran a paxton on my '91 stang so maybe this will help. The oil in the boost line in normal, gets sucked in on decelleration. As far as the idle going up and down; I've posted this before but will say again; you need to adjust the TPS sensor[black sensor on throttle body] Get a digital meter and look at DC volts, engine off, ignition on. The meter will probably read 0.8 volts. Undo the the 2 screws holding the TPS sensor and try and wiggle it until you get 0.997 volts.If there isn't enough adjustment,take the sensor off and enlarge the holes slightly and reinstall and try again. Do not adjust for more than 1 volt. This will richen up the idle and settle down the computor trying to compensate for the extra air going through. Perry.:cool: |
