GN runs bad

[rb84gn]

I got an 84 gn with a new motor and most sensors are new but
it run very poor after about 75mph then it set a code 32.
The car has got cold air new 160 thermo jet chip boost gauge
oil temp volt and soon knock.

Also cant get past 11psi of boost


thanks

a code 32 is EGR Valve System is malfuntioning.

CODE 32

Trouble Code 32 indicates that the Exhaust Gas Recirculation (EGR) valve diaphragm is not where the ECM expects it to be. The ECM controls the diaphragm with a Pulse-Width Modulated (PWM) waveform. The EGR has a vacuum bleed solenoid that adjusts the vacuum applied to the EGR valve based on this pulse width. If there is sufficient vacuum at the EGR valve, a switch closes to send a signal back to the ECM. The absence of this signal is the bases for code 32.

The conditions for setting this code are:

no vacuum to EGR (switch open), and
Code 33 or 34 (MAF error) is not present, and
engine running and LV8 is less than 100, and
coolant temperature is > 118 deg F (48 deg C), and
the EGR solenoid duty cycle is < 65%, and
the above conditions are met for more than 25 seconds



Typical causes for this code include:

1) Faulty EGR valve-to-ECM connection
2) Plugged EGR passages and/or sticking EGR valve
3) Defective EGR valve
4) Defective ECM

would that make it run bad after 75mph or is there something else that could be wrong with the car

start with some basics:

-what kind of plugs?what gap?
-what kind of gas?
-stock fuel pump?

get that knock gauge in too.

I'm running a set of bosch platnums gaped at .35

As for fuel its 91 oct because thats the highest in North Platte NE

It's the stock fuel pump but going to hotwire its weekendwith some 10 gage

Where to get a good knock senor at and how much.

if I'm not mistaken, PLATINUM PLUGS are very bad for our cars!!!!!

 

[rb84gn]

i guess that would be a part why it's running bad
what would you recommend?

 

[xxninja]

turob buicks like genuine Ac delco parts
No need to pay top dollar, for a name tag. when it doesnt help at all

get ya some
Ac delco's

AC-CR43TS

gapped @ .35


reccomended from www.gnttype.org
