Reduced engine power
Car starts then I can hit the gas pedal once
then dies out I bought a new pedal and took
the throttle body off my husband car to see
if that was the problem and still the same
thing but if I clear the check engine light it
will run until the check engine light comes
back on can someone tell me if it's my
computer or what
You can go to most parts stores like autozone and rent the scan tool to read the code or codes that will tell you why vehicle keeps shutting off.
It says throttle body correlation
Check for a blown ( ETCS ) Electronic Throttle Control System fuse. Check owners manual for location of fuse in fuse box . If no owners manual go online and type in owners manual for year, make and model of vehicle will take you to sites for manuals for your vehicle.
What trouble code do you have? -Jim
P0068 and p0102
Sounds like a problem with the mass airflow sensor. The P0102 is low voltage at the sensor and the P0068 means that the airflow going past the sensor doesn't correspond with the throttle position. Check the wiring going to the mass airflow sensor. It could be damaged or unplugged. Also, if you have one of those K&N air filter kits the mass airflow sensor is likely contaminated from the oil that goes on the air filter. Get rid of it and put the stock air filter system back on. It's a cold air intake system from the factory anyhow! HTH. -Jim
