Hey guys,
1999 4Runner
3.4L
Auto
195k miles
locker
immobilizer
So I have a stock 99 3rd gen that will sometime die immediately after starting, and other times fire right up. The hard start doesn't matter if I hold the starter cranking or not. The truck has the antitheft ignition, so after it doesn't start I have to turn it all the way off and wait a sec, then try again.
Stranger issue, the truck will run pretty well after it starts, except sometimes it'll wanna die if not moving, usually while in drive at a stop light or something. It will just start idling low for 2 seconds or so, then just die. NO CEL. Will usually fire right back up. Truck seems to have full power when on the throttle.
Idle is normal for the most part. Will idle in the driveway in park at 700 rpm and not skip a beat for days. No CEL. No smoke. No Rust
Here is what I've done so far:
Replaced entire throttle body (2 different ones) This includes IAC, throttle position sensor, etc.
Replaced entire intake
Plugs, coil packs, wires (2 different sets)
fuel filter
2 different mass air flow sensors
oil change
searched high and low for a vaccumm leak, couldn't detect one.
and no change whatsoever.
I'm really at a loss right now and have reached my patience ceiling. Help would be sincerely appreciated. And if you come over and help me i'll feed you beer and pizza.
