Ok i haven't pulled the codes but the shop "said" they changed fuel pump and filter. Tps, maf, and distributor module. Never heard of this one. He only charged me for the pump and filter.
The symptoms as of now include:
Misfires, stumbling while idle, stumbling while driving, sudden gust of acceleration after sluggishness, truck will stall out then re gurgle itself back to life 90% other 10 I have to turn key manually, truck will stall at highway speed, I throw into neutral and will fire right back up.
When it happened the first time I got loud backfiring as well.
Could the cat be clogged causing the sluggishness? IAC? Egr? I'm lost with this now
