#37 of 39 Throttle body blues by gearhead11 Feb 27, 2009 (7:42 am)
I have an 84 crown vic 5.0 throttle boddied carb. I just can't seem to get it to idle right. it either idles high or too low and when it idles low it surges. Iv'e replaced dist cap,plugs,upgraded wires and hotter coil. I've checked for bad vacuum lines. Any ideas? Is there any way to bypass the eec-iv computer and run a regular carb?
#38 of 39 MAP to MAF conversion '90 CV by dj7trypp May 19, 2009 (10:41 pm)
Anyone know how to switch the computer from a manifold air-pressure sensor to a mass air-flow? Do I have to replace the entire induction system? If so, what are some good aftermarket choices?   Also, the engine likes to cut out when I go around corners... I can''t even find anybody that's had the same problem.
#39 of 39 98 Grand Marquis by ts128 Jun 22, 2009 (4:22 pm)
My Grand Marquis has been doing some strange things lately, it all started late one night when my daughter went out to get something out of the back seat, when she opened the left rear door the car began to turn over like it wanted to start, then it stopped, the next time it did this was when we were driving it, it started grinding like crazy, so the first thing we thought was to replace the starter, didn't help, next was it went to FOMO where they said it was a loose wire under the dash, it didn't happen again for two weeks and then it started doing it even worse, so I inspected the steering column for wires rubbing or loose, found nothing, checked the ignition switch and all looks to be good so I moved on to the starter relay and changed it. I'm hoping this fixes it but just wanted to see if anyone else with one of these cars has experience this. Thanks, Tim
