Need Help Fast!!asap
I did a plug change on my 90 F150 4.9
I put autolite plugs in reconected everything
I started it up and took if for a spin and it is missing worse than it was before I changed the plugs.
I took it to a friends house he says that the metal thing inside plug wire on cylinder #5 wasnt connecting to the plug.
I got new plug wires cause the wires needed changed anyways.
I started it up and drove it with my friend inside he said to get some injector cleaner in it.
I went to advanced auto with my Bro and on the way It felt like I had NO power whatsoever. I had to have it mashed in 3rd going up a small hill. I got to a stoplight and notice TONS of whitish colored smoke behind me. IT feels like its missing like nuts with NO power. I took it back to my friend and he Took the temp gun to the Exaust.
Back CAT= 352
Front CAT=200something
Back header=497
Front Header=293
He said that he thinks the front Cat is clogged. I need to know that he isnt BSing me or if something is Screwed up. To me it sounds like the CAT is clogged.
Where could I get a new Front CAT?

hmm ok before you start replacing the cat/cats what is your temp reading on the dash? or should i say what is the motor running at temp wise? is the check engine light on?. what about replacing the cap and rotor too?

Definitely sounds like a clogged cat. You need to shoot the temp gun on both sides of 1 cat and look at the difference between the two numbers. If it is hotter at the rear than it is on the front by more than 10 or 15% then you've got a clogged cat.

I took the flanges off.....unbuckled the pipes. Talk about a PITA those bolt were something! lol. It runs ALot better but its still missing a tad from somewhere so I think the truck might be getting sold. I Know the CAT is clogged though.
I really don't want to buy an new CAT they are EXPENSIVE!!!!!!
SOOO.......are there anyway to UNclog the CAT. I know My Step-dad used CLR and Drain-o to unclog the CAT in the Corvette. Thanks for the REALLY fast reply I needed it.

does a cat make "tons of whitish colored smoke"? Ive always thought that it usually means burning coolant?
