Intermitting Problem Causing No Power
#1
My car 87 gxl, has this weird problem where one minute it will run fine then will have no power, fluctuating idle, engine shakes really bad-worse when I give it gas and give off an exhaust note of a wildy ported engine.
Now so far Ive checked, replaced, fixed-
leading coil
spark plugs and wires
fuel filter
full tune up
pre cats replaced by straight pipe
catco high flow cat to replace main cat
tps set over and over unpluged it too nothing changed
anything else I should check??

Do what ford Techs call "The Wiggle test" basically grab various parts of the underhoos wiring harness and give it a good shake, twist or other movement and see if the problem changes. if it does you may have a bad connector, or loose or broken wire.

Add new grounds to everything. It seriously makes a world of difference.
Reground the lead coil, and the main engine ground. Or something like a new ground going up to the alternator mount bracket will do the same.

My car smoked a storm and had no power at all until I spend 4 bucks and regrounded my lead coil, bam no smoke and alot more pull (in comparison to before).
Ever since then I have regrounded anything that has given me a problem and not surprisingly it has usually solved or aided the problem.
