1989 Camaro 350 TBI T-5


Alright here's the deal. I am sick of this car, I cannot figure out what is wrong with it. If you give me an idea and it fixes the car I will send you 25 dollars over paypal. And I will trust me.

Car runs fine until something happens. The SES light comes on. The car bogs down, when you WOT it gets VERY loud and the RPMs SLOWLY increase and barely can get over 3000 RPMs and SOMETIMES back fires in the intake. Shut the car down and restart it it runs perfect after that. I will be getting a video of this tomorrow.

When I pull the codes I get 24 and 43.

24. When engine speed was between 1200 and 4400 RPM and throttle position angle was less than 3%, the MAP signal showed low voltage (high manifold vacuum) for at least 5 seconds.
(http://www.austinthirdgen.org/index.php?pid=27#5LTBI)
I just saw this and am unsure on how to fix this... Any ideas?


24. Circuit fault in vehicle speed sensor
(http://www.thirdgen.org/service-engi...ht-error-codes)My car does not have a Vehicle Speed Sensor

43 The ECM did not detect a knock signal during near wide open throttle operation with coolant temperature above 194° F or the knock signal was present for 4 seconds or more during normal engine operation.
(http://www.austinthirdgen.org/index.php?pid=27#5LTBI)
Replaced the Knock sensor


43. Low voltage at electronic spark timing circuit
(http://www.thirdgen.org/service-engi...ht-error-codes)
Replaced the ignition module


What I have replaced on the car (was not meant to fix the problem):
Alternator
Battery
Oil pressure sending unit
ECM
Aftermarket Speedometer

Doesn't matter hot or cold. Gas doesn't matter either. Besides aftermarket speedometer no.

Can you double check the brown ground wire on the electronic spark control module? may be loose or broken.
