    I’ve been chasing down a non-functioning EGR for a few weeks now. I’ll spare you the details of individual components testing but suffice to say EGR, EVP and EVR have been thoroughly tested and verified good. I think I’ve finally narrowed it down to a grounding issue, hoping someone can confirm...

    Hey all - for todays lesson i think I discovered an interesting fail mode on my EGR position sensor. I’ve been pulling my hair out trying to figure out why I’m getting intermittent 33 and 34 codes. Bench testing my EVP (per Seattle FSBs Tech write up ) it hits the resistance range endpoints...

    swapped in 1996 explorer injectors in my 96 Bronco 5.0. They are the flatter disc style as apposed to the OEM style with the little pintle at the end shrouding the injector holes. Do I need a spacer when installing these in the intake? I’m having a rough idle I didn’t have before. Also...

    Recently my 89 Ford Bronco v8 5.0l tachometer has been bouncing randomly up and down dramatically without acceleration. From 2,000 to 6,000 and back down again without a change in the actual RPMs. I recently got a Code 34 which could be one of three things 1. EGR control circuit fault 2. EVAP...

    I have some leftover parts from my frame-off on my '89 351. Some are not pretty but work. Some are nice and work. I have them listed locally on Craigslist so they may sell locally. I was saving this for "spares" but decided I need them gone. Prices are shown exclude shipping Re:side glass If...

    this is a 91 302 w/ E40D 4x4 4:10 axles w/ limited slip... its an f-150 with a 36xxx on the 5 digit odometer, but i dont think there are any differences that would change the diagnosis compared to a bronco we just bought it, so the history is vauge, plus the guy lied about at least 2 things...
