Hey guys iv got a blazer problem yeah dont we all? Hah okay so ONLY COLD will my blazer sputter going from first to second gear if i give it alot more gas then normal it wont do it but just a normal cruise off the line it will sputter, iv already replaced fuel filter and giveing it a full tuneup (it had to be done anyways) it only happens when the truck is cold any ideas???

 

And my fuel pressure has been checked and is fine

 

I'm having a similar issue, did you ever find the cause?

Thanks,

RAP

 

make sure the air induction system is tight,,,no leaks from the air box to the TBI
