That'd be awesome. I assume they bolt up the same?
Still 2 bolt like 304 ill dig it out I got given it in a box of parts
Fitted the new starter and car cranks and idles mint.
Engine bay pic for extra likes:
Swapped alternator belt from an 11a1145 to an 11a1130, this holds the alt in tighter to the block and avoids the alt fan fins chopping my cold air box.
In other news, still throws codes and goes to limp mode in the trans whenever full throttle is used.
Yeap, but swapping sensors doesn't help. It's either tune related or something funny in the wiring like an overloaded earth, or RFI etc
What code is it popping up?
I've noticed adding extra earth to harness at passenger side head o2 sensor & map sensor some cars will run alot nicer,suppose it wouldn't hurt for tps too.
Vs 304 setup in vp ute sometime went into limp mode if you stalled it up & let it rip...traced it back to power wire fuse(12?) for the auto not getting constant power.
Cousin once had a weird intermittent issue with his vs auto ended up being solenoid or something in box
I am getting 21 and 35
21 - TPS voltage high? Might need to adjust the position of the TPS on the throttle body (rotate it). Might also need to check the travel of the TB blade with someone in the car pushing on the pedal to confirm it's not going to far.
Pretty sure we tried TPS position when this problem first arose.
Good idea about blade angle. Although I'm sure it has faulted at 3/4 throttle before (not just w.o.t)
Those both seem to be either tps related or something to do with that aftermarket throttle body.
Have you checked readings to see if it's witinin spec range for closed throttle & WOT...maybe it's tripping tps out?
Think I read on delco site albeit for ls throttlebody if you file too much tps can go out of spec range & then get fault codes or limp mode
That sounds very much like what mine is doing
Have you tested the TPS using a multimeter? I'm on my third OEM TPS in as many years.
Tps should read 0.5v closed and nicely go up to 4+v.
Only the ecu datalog on it.
I'll ask immortality to recheck the log. I can't remember what closed value was, but I thought it went 5.0v at w.o.t
The log shows it's going all the way to 5.0volts so that will be why it is setting a fault code (DTC 21 and it's also setting a IAC motor fault DTC 35). Closed throttle is 1.06volts so you need to rotate the TPS sensor so it lowers the working range.
I think it is already as low as it can go, but will try and take a look this weekend.
Although if tps voltage was out, then wouldn't tps % be out also?
It starts 0% tps from what ever the minimum voltage is.
If you can't rotate it any further close the blades too and use the idle air bypass screw on the manifold to get iac steps to like 20 steps hot idle
Great idea mate. I will try and find time to try this soon.
I will report back obviously.
