HELLLP!!! engine cuts out at 2100rpms

[busybeezturbo]

My engine (89 7mgte) cuts out ay 2100rpms and starts running again at 1400rpms hard to start takes 6-8 tries before starting.

Do a full tune up. Timing could be off.

[ILLICITDRIVER]

timing is controlled by cam sensor. might want to check your cam position sensor and as userlain said....complete tune-up (plugs, wires, oil change, throttle body cleaning)


also, check the connection to your coil packs, might be loose due to time.

check engine lite on?

[busybeezturbo]

yes check eng.light is on I did the throttle body cleaning that is when problem started. have new platinum plugs just changed after prob.started

[busybeezturbo]

could this be o2 sensor???

[busybeezturbo]

I noticed that when I unplug MAF the eng. revs to 2800rpms before cutting out to 1400rpms

Please check the induction tube most likely there is a split in the tube it's a intermittent problem

[busybeezturbo]

Ihave taken off all intercooling piping and other hoses and checked them for cracks and holes.didnt find any.

[busybeezturbo]

Ran code check and came up with o2 sensor code,AFM code and Intake Air Temp.code will try changing o2 and AFM (black box). B

[fredk]

can you give us more detailed meanings of the codes?

[busybeezturbo]

do you need numbers #21 o2 sensor code, #24 Intake Air Temp,#31 Air flow meter signal. Is that what you wanted to know?

[busybeezturbo]

The car was cutting out at 2100rpms when I unpluged the AFM car started cutting out at 2800rpms.

[anuthaCamry]

wow, it sounds like a loose or disconnected cable. Or a blown ignitor and/or distributer. use a timing light

[busybeezturbo]

I have trouble code chart for MK1,MK2, MK3,MK4 Supras.you have codes you need to check? If so add to post and I will check them. B
