SR sluggish

[Corey]

ok so i just noticed today my car was acting like it has a realy bad boost leak (motor and car shaking and running like crap) but i checked all of the vacum lines but still no luck. the boost gauge showed no signs of abnormal vacum readings. anyone have any ideas?


car: 89 SR Hatch

Dead coil, bad spark plug-boot, compression, injector pulse, maf many options on that one. More info needed.

yep that one is blown and the one above it (engine con.).. what is the engine con for?

just changed both and still no progress. checked the plugs, coils, and all lines. the exhaust is shaking like crazy as well as the motor. and will back fire every once and a while.

bent valve?

 

[robertftw]

dumping to much fuel cuz of bigger pump.

or it crapped out like a walbro does. my boy had a brand new one and it crapped out in 2 weeks.

 

[robertftw]

check fuel pressure, 35psi at idle.

Sounds like a similar problem I had with my KA. Checked everything, couldn't find what it was. Motor was shaking like crazy! Ended up being the O-rings to the injectors. Don't know if that could be a possibility with your SR though.
