Hey everyone, I have an odd issue here.

After about 20 minutes of driving the car starts sputtering (it feels like it's running on 4-5 of the 6 cylinders). There's no CEL on. If I pull over and immediately try to start it, it will either hesitate and restart with a rough idle, or it will crank and the crank has a dead spot in it like it's catching something.

After I let it sit for 10-15 minutes, it will start and run just fine. (If I'm on the highway and cut the engine, after about 30-45 seconds of coasting, it will do the same thing) But after another 20 minutes of driving, it will start acting up again.

Another thing worth mentioning is that after I try to do an immediate restart, the tach won't work until the car either starts acting up again, or if it sits for that 10-15 minutes.

I've seen some threads about the TPS and the CPS. Do we think it's one of these?

Pull your codes. Codes can be set even though there is no check engine light

Oil in the spark plug wells. Free to temporarily fix.

If the tach is involved though, dropping to 0, that's a sign of cam position sensor.

Really that obd I code reader is worth buying. Counting flashes gets monotonous after a while. Ford obd 1 code reader Innova 3145 now $26 on amazon
