Hello,
Car Info:
- 1991 Vitara MT, 2 door, G16a, 4wd.
- 257000km / 160 000 miles
- Plate in engine compartment.
- TYPE: ETA01V
- LAK625K17 (SWE, car has actually been sold in neighbor country FIN)
- No AC
Ok again some fun with my degrading EFI system.
Last time I diabled IAC with aluminium tape and plaster of paris. ( https://fixkick.com/forum/thread-high-id...2#pid13982 ). Build a vacuum stealing hose to cabin with moped's fuel valve as a IAC "bypass-hack-hand-throttle-hack" to rise RPM when cold.
Also ISC is kaput, can't find replacement part. Also idle RPM tuned by some carburetor guy before I bought this 6 years ago. Guessing because of dead ISC.
Anyhow car is in condition it is working and driveable, but now that it has been sitting for couple of months during winter, there is a new issue.
The daspot (or what ever it was called) that slightly presses throttle on cold start is "sticking". Yesterday (engine warmed up) I noticed that I have slightly elevated idle 1200 RPM. When arriving my destination I did couple of turn of and start again tries. Most of them resulted to 900-100RPM which has been "default idle" for this car after that carburetor guy poking it.
Anyhow one start resulted to 1400RPM. I went to look under my hood and the throttle cable had zero slack, bit pulled back. I did couple of restarts until it resulted to 1000RPM and there is couple of mm a slack in now.
So to my understanding the daspot thing is getting stuck intermittently. I see it has rust outside, so most probably it has rust inside too.
Is there some easy way of just disabling it without pissing the ECU? Like pulling some electric cable or vacuum hose. Ofc if I need to pull a vacuum hose I need to plug it, but thats easy. Golf tees work like a charm.
I am guess I can get it started on cold weather with slight press on throttle pedal and opening the valve for my hack for IAC. Anyhow seems to be eager one to start even if its -30C / -22F outside.
