okay i got another rolla gts 1990 redtop

now the guy told me it misfires a bit, so whatever

well i changed the plugs wires cap and it drives good and then out of no where 10minutes later or so it dies down again and theres no pickup until 4500rpm

so i check AFM and play with timing , AFM did nothing but timing improved it once again out of no where it dies down again but this time instead of 0-4500rpm is dies down at 2000-3800rpm


any guesses or actually anyone know what it is?????

Could be TPS...

Air leak in your intake tract?

no leaks in intake tract
and i thought of TPS aswell but would that affect the engine all the time not jus at certain rpm levels of temperature levels??
