I finally got the L98 started, but when I give it some gas it doesn't respond. It keeps a constant RPM. I'm going to check the TPS voltage now if that will make a difference. Anyone know what would cause this?

 

Definitely check the TPS. Is it setting any codes?
(did you make sure to reconnect your throttle cable? )

 

lol, yeah, the cable is connected . No TPS codes either .

 

If you open the throttle blades and don't dump any more fuel in the car will sputter and die. Make sure the blades actually open when you hit the gas. Could be that the cable is broken internally and you're getting no opening of the blades.

 

I was opening the blades by hand with the lever on the side of the throttle body.

 

Did you ever get your injector problem fixed? I thought I read something in another post.
The obviously are firing now or it wouldn't run at all.
Do you have a scanner to verify that the ECM is seeing the TPS voltage?

 

so even opening the blades by hand the rpms wont increase...id say its all TPS...like said get a scanner to read tps volatge to the ecm

 

ok try this for ***** n giggles...reset the computer it may work

either from the battery of directly by the ecm connections

 

Yeah, I got the injector situation worked out. I don't have a scanner to read the TPS, but I do have a digital multimeter. That would work for reading the voltage, right? The center wire on the TPS should read .55 or thereabouts at idle IIRC (?)

 

Yeah, roughly .54 at idle and I think 4.0 at WOT.

 

Turn on ignition, but don't start the engine.

With a scanner: plug in the scanner and read the TPS voltage. It should be 0.54Volts +/- 0.075Volts


If out of spec, loosen the two screws holding the TPS to the throttle body, and slightly rotate the TPS up or down, reading the voltage until it comes into specification. Tighten screws. Using the throttle lever, rotate the throttle to WOT (wide open throttle). The TPS voltage should be over 4.0 volts. Close the throttle again, and then slowly open it to WOT, observing the voltage reading. It should increase progressively and in a linear fashion. If it sticks or jumps or falls off at all while doing this check, that could mean a bad TPS switch and could be a cause of stumbling and driveability problems.

After setting the correct voltage, turn off ignition switch. Remove jumpers/scanner and reconnect the TPS connector as required.
