Hi,

Starts, runs and drives perfectly from cold, if you switch off and start again whilst the engine is warm then after 20/30 seconds the engine sucks air, lumpy idle, doesn't stall but almost sounds like it will and that it's not running on all six, backfire noise when under load, then will clear itself and run perfect after a minute or two.

I have cleaned the IAC and throttle body, put injector cleaner in the fuel tank, checked all the vac pipes, sprayed with cleaner to see if the idle increases, check connections to sensors.


no DTC's, fuel pressure in the rail seems fine.

Any idea's, thanks in advance

Maf

 

My '97 does the same thing. Did you figure it out?

 

The OP hasn't been around since 2015!!

You're better off just starting your own, new post.

 

LOL, did not notice that! Thanks, will do.
