alll the time, youll be driving and it will suddenly loose power and spudder....then kick in to full power and pull like a bastard.

You may want to check the wireing harness and the connections to the injectors and the FICM. They sometimes work loose.

Have you scanned it ? Are there any codes? Do a powerbalance and find out which cyinders are not contribing !
