My check engine light came on because my knock sensor for a wet, so I replaced both knock sensors and put everything back together but the check engine light is still on. Do I need to go get the computer reset to get it to go out?

And it says engine power reduced. And won't run. Turn it off for a few minutes. Then it w I'll be fine or in hook battery

This is an intermittent problem but is increasing in frequency. Truck has 200K in miles. My research on-line yields mostly speed sensors may be dirty or need replacement in from wheels.

every time you start it every anywhere i start my vehicle

first time this has ever happened. battery completely dead. was fully charged and showed no signs of weakening. tried getting a jump, engine struggled to turn over and all electrical dead. no lights,locks, windows. strange rapid clicking coming from fuse relays in engine compartment. jumping by bypassing the battery, lights came on but engine struggled to turn over. Then all electrical went completely dead, even with jumper cables still connected and other car running.

Had heads replaced due to a bad casting (castech heads) And they cracked by the headbolts. Picked the truck up and it misses like a bastard. I can't have the truck down for another week as it's our only vehicle and we have 3 school age kids. Any ideas?

Occurs only when engine warm/hot ,at idle in drive launching from a stop,this occurs consistently 0-4%tps p0300 was stored history, no other codes,no reduced eng.power.( this feels to me like a carburated engine with a bad accelerate pump or blocked off idle port) cleaned/ wiped throttle plate area appears normal and no codes throw while road test even as condition occurs,I have a tech2 but no access to TIS . the RSS system is not op and several hard codes stored in that.air filt /intake appear norm.engine power underload thru hi way speeds are normal.
