Kk not sure how to word this but here it goes. My car idles like a dream but it bugs at half or full throttle basically as soon as the gas is touched.

Thrings I have done;

New dizzy p, plugs and wires
Test values on the following thing;
Map sensor, OK
Tps sensor but had wierd values closed throttle was 4.9 volts full open throttle 1.8
Tested vacuum presure and it was at 17psi
Compress was 190 across the board
Leak down values are all normal
Disconnect fuel pump and tested volts going to the fuel pump 7.8 V
Timming did not jump a tooth it is bang on
Disconnect ecu and tested with other p61 that I know is working

Any ideas ???

Thanks folks

 

That's weird, try and unplug the ecu for at least 5 minutes and then plug it back in and drive. any check engines?

 

There should be 12v at the fuel pump. That might be the issue.

 

accel slow and if it revs all the way smoothly it is fuel not holding pressure.
