USo I searched all over, messed with Honda acura for years up until about 06 then couldn't find the time new house family ect.. I've searched all over Google then remembered I joined ht years ago..

I cannot find any info with problems like mine 93 del sol si z6 was all stock when I took it in on trade to restore

Pulled the motor cause it was caked in oil to clean, do a stg 2 clutch masters clutch and various gaskets ect..

It sat about 6-8 months busy with family kids baseball ect..

So 2 weeks ago I finally got it all wrapped up odds ends ect, sounded great ran great shifted great no leaks. I drove it a mile down the road and was coasting down a hill in 2nd let out the clutch took it up to 4500rpm shifted to 3rd and bam it bogged way down cel came on oil light flickered some then stopped.. Wouldn't rev past 2500 rpm or go over 20 mph..

I've checked all the wires ect, next day I went to check the cel code and my cel wasn't on, my scan tool is obd2 so I tried jumping to count codes..

Unplug map sensor it dies, tps it seems the same ect.. I did pull a 02 sensor from a y8!header and hardware it cause the plug was missing but it don't seem like that would cause a issue, I unplugg 02 cel comes on.

I unhooked ecu and battery still same problems when I plugged them back in

Car starts up, two times I had to pump gas and it started had gas smell and lighter color smoke come from it..

Never had a car go into limp mode on me dunno where to start, check timing? Injectors fuel filter? Ect

Just can't find anyone with my same symptoms, everyone else in limp mode revs higher or it's just a cut out mine is horrible and barley runs..

Any feedback is appreciated thx

 

Pull the code.

 

There is no cel, can't pull the code..

 

Pulled spark plugs they was new, now the are caked In black soot just dry

Pulled cap off, some oil in the bottom rotor looked rusty

Pulled fuel line off filter turned key gas shot out fast so fuel pump is pushing good flow, fuel rail checked out fine

Put new plugs in gapped ect, unhooked ecu and battery for 20 minutes and nothing still runs like **** barely runs have to pump gas to get it running

Pulled out all 4 wires while running ran for a minute than finally died out, all 4 are getting spark

Sensor/bad distributor cap rotor ect..

Temp sensor wiring has been hacked or cut and re wired and 02 sensor was cut and plug tapped on..

 

Check timing.

 

Yea that was my next thing to check this weekend..

Thx

 

Does the cel come and then turn off like when u first start it up?

 

Yea

 

Possibly that ect wiring or timing.... Not many things make a stock car go into limp mode

 

Checked timing= good, compression 195/200 across the board..

Then I finally got a cel light YAY

Jumped it checked my flashes got 7 shorts so that is showing TPS

Guess I'll find a tps and switch it out

 

Pulled a TB from another z6 put it in was colder the other day it wouldn't start at all..

Dunno unless wiring is bad or ground isn't grounded good.. Timing looked good ect..

New spark plugs in it are already blk 2 cylinder are getting the plugs damp with what seems to be gas

Any ideas?
