Had her since 2007. Driven about 30000 km my self, I donīt know how the previous owners did keep her, but I have tried to keep everything in mint condition.

Small mods, but majority is stock... NA engine. The car is 87.

Everything was working great until the end of this summer.
-Now the idle is pretty poor, idles around 600 and the idle is bouncy.
-When on engine brake, the engine revs donīt go down smoothly.
-When keeping the revs around 2000 there is small humping
-Now this new thing emerges, I can feel some hesitation when accelerating. The hesitation can be noticed on whole rew scale. Itīs kind like a little nod, a nod that happens once on a while...

I have been thinking that are these the final moments of my engine, and do I have to consider a total overhaul of my little 13B ?

 

TPS cal combined with your average poor earthing 3800 hesitation issue

gee,, that is what 90% of the posts in this sub forum are about.. i suggest you search

 

TPS has been adjusted on this week... Did not do a thing...
Hesitation not only on the 3800, but hesitation on whole rev scale...

 

compression test

 

Ok, while we were adjusting the TPS we tried to adjust the idle...
One needs to put a jumper wire in a connector which has two heads/holes... That little green connector cannot be found on this Euro spec model...

The idle screw wont do a thing without the jumper wire ?

 

Are you referring to the screw on the BAC? I usually just unplug the BAC when I set it.

I recommend you verify your idle and thermowax settings on the TB itself though. A lot of times just fiddling with the BAC screw can make things worse, "band-aiding" the actual problem.

 

those brit /euro ones are oddball, seems the ecu uses 12v senders ( and a dizzy ) and is more related to the 12at/ GSL-SE ecu
( i even wonder if the injectors batch fire )
try and find the pin at the ecu and ground it , and get revs below 1000

there was an example on aus rotor where we tried to sort this one out before

however i expect the hesitation issue is the same as everyone else
,, deteriation of the loom joints where the various sensor earths and shield earths tie together in the loom,, just out form the ecu
resolder those crimps and most people have it fixed

 

before you go crazy change the spark plugs and plug wires if you have a bad wire it will reak havoc

do not set anything untill you do them first
