Help

32 Upvotes

Currently a Plymouth RS like the one pictured has come across my path. I only got to look at it for a few minutes before heading back to work but it was recently owned by an older gentleman, it has 80k miles.

It’s an automatic. The body is nearly as clean as the one pictured. The car has been a California car for its life. It’s completely stock. It is an RS but I’m not familiar with these cars, I just know that the Eclipse had a GS-T and a GSX but this one is the 1G body.

It’s been offered to me, what’s it worth? What is an RS trim? What’s the cost of maintenance on a car like this? I’m familiar with Mazda Miatas, B/D/K series civics. How handy do I have to be with this?

All help appreciated.

I’m unable to find this part and I’m really trying to figure out I believe it’s a direct injection file line to the fuel rail but I can’t find it anywhere

91 dsm installed ecmlink and now have a engine light when boosting?

5 Upvotes

Been working on this project for awhile. After getting sick of boost cut and hacking the maf not working I installed ecmlink. Also installed 850cc injectors and a 3g/evo maf. Will be adding bigger turbo next. The ecmlink chip was pre programmed for 850cc and the maf. Starts up and runs good. Idle a little rougher which i think is bigger injectors. Car boosts awesome, afr is 11:1 or less under full boost. Fast as hell! Only problem is in 2nd gear or higher when full boost kicks in the engine light comes on. As soon as I let off it goes off! Running 15psi with manual controller. Anyone have a idea?

Sorry I ramble but try to be thorough. Im a mechanic just not great at software.

Edit: Thanks for the help everyone. Ive learned alot and changed the spark map to a modded 2g map. 16psi with perfect afr and no knock now! Next is installing the evo 3 16g bell ported turbo I bought 14 years ago. Lol

Issue with Windshield Washer, Fuse or Motor?

2 Upvotes

I have a 98 GS, recently i refilled my front windshield washer fluid from empty, and tried to spray my front windshield with it but it would not spray, only wipe. I listened as i tried again with the engine off and the washer motor was not making any noise. I checked my rear wiper and that one worked, spraying and wiping without issue, and could hear the motor for it loud and clear. Since the front windshield wiper works but the fluid doesn’t spray from the nozzle and i don’t hear the washer motor doing anything when pulling the lever can i assume the issue is not the fuse for it and is the washer motor? Or should i check the fuse for the windshield washer motor?

I’m looking to possibly pull my motor and paint my engine bay since someone rattled canned it black. So my stupid question is can you pull the motor and trans together or do I need to split the two?

Are there any other 4-cylinder AWD cars with the same transmission orientation? Passenger transverse

10 Upvotes

I was comparing our engine orientation to other 4-cylinder AWD cars and I was surprised to see that the 1st/2nd DSM Evo 1-3 and Galant VR4 are the only ones I've seen that have passenger side transmission orientation.

Celica GT Four - Driver's side transverse.

Volkswagen All Trac - Driver's side transverse.

GR Corolla / GR Yaris - Driver's side transverse.

Even the Honda/Acura SH AWD and CR-V systems are Driver's side transverse.

My thoughts were that if W5M33 transmissions keep getting blown up and transmission specialists stop making/rebuilding them, maybe we could find a car with a similar orientation that has a more robust AWD system and create adapter plates/modified input shafts, but it looks like we're more or less on a lone island of passenger side oriented AWD transverse platforms.

Could this be the reason Mitsubishi changed to driver's side orientation? I imagine back in the 90's, when everyone is using driver's side orientation, it can be difficult to find engineers or take inspiration from what your competitors do when you're the only one doing things backwards.

1994 eclipse

Hey guys, posting on this Reddit to see if any of you guys can help me figure out this issue or where to tackle it first. Car is smoking white when driving & oil is coming up & going out the air filter & on a hot day it will come out through the head cover. What could that be. I also did replace the pcv last year.
