My 86 gxl---I am not talking about a 3800 hesitation,but right about there at full throttle,my car starts to take a **** and will not come back around.It feels like some one stuck rags in the tail pipes right at about 4000 rpm at full pedal.Its starts to spit ,and burp and **** and will not hardly move.If I stick it in neutral and rev it up its fine.If i slowly give it gas it still will not climb hardly above 4000 rpm.The car has no cats so thats not it.Any ideas.I just replaced the plugs hoping--but that did nothing.---help me out

any engine codes?...see if you can get a check engine light



adjust the tps



sorry that is all i can think of

What is the condition of your six ports and secondary injectors. Mine had no power past 5k. secondaries dripped, and the six port shafts would not rotate.

How is your fuel filter and fuel pressure?

Sounds like the secondary injectors are not opening. have you worked on the upper manifold and disconnectd the secoondary injectors?

Vac leak maybe?

Ok,i have had some guys tell me the secondaries,or the connectors.I had a radiator,mastercylinder,and the actuall housing behind the waterpump resealed.Is it possible they might have undid a clip or something---Hell i dont even know where the damn connectors are at.

under the upper intake mani you will have to remove it i believe to check it out

good luck

thanks

The connectors for the secondaries are under the black rubber intake tube, passenger side in the upper intake you can't miss the two injectors... Also how's the fuel filter? If not sure, definetly replace it.

Thanks guys for the help,today will be a busy day.
