Replacing the injectors and rail, plugs ht leads and coil pack still to no avail i have also ran a compression test on it cylinder 1 and 2 are at 135psi and 3&4 at 138psi i am running at out ideas the ford mechanics want to charge me 90 quid for a basic diagnostic however i have also plugged in an obd2 reader in the vehicle and has given me a reading of 2 codes "random and/or multiple misfire" and "cylinder 1 misfire" i have cleared the codes the problem persists but the codes dont come back either. I hope someone can help
