[@miz180]

What a G , thanks dude! I’m gonna remove a sensor see if this is why my acceleration is restored

My Acura tl type s, only 87k miles, cats shot out into the exhaust, I thought my transmission was going out but on Honda they have a safety mode that’s not limp mode but doesn’t allow ur car to go over 4500 rpm’s. Took me forever to find out since the car didn’t throw any codes

[@user-pu2vw6ny9d]

This sounds like my exact problem. Only I have a Mitsubishi. Gets stuck at 4000rpm.

Did it drive like it had a misfire?

[@cadetauto1769]

@@LUISTORRES-vx4mg yes, should take off the exhaust from the jpipe and if it runs better then you have a clogged exhaust

[@LUISTORRES-vx4mg]

@@cadetauto1769 I thought it was my fuel pump, the car runs really good but when I’m at a stop or red light, the car starts acting like a misfire

@@LUISTORRES-vx4mg mine would be weird whirling driving and almost give out when coming to a stop, drilled a hole into the exhaust and it started running better, took off the exhaust and drive like new

Do you know if back pressure can cause a carb to spit out gas into the bowl at higher pressure? My needle and seat will stop it but once it needs gas to fill up the bowl it shoots out like the belagio in las vegas.

I have a cat delete after it fell apart and it may have clogged the muffler.

Can a clogged exhaust cause a rich idle?

[@whyingo7964]

A clogged exhaust can throw off the 02 sensors which could cause a rich condition.

[@Thirdgen83]

@@whyingo7964 I don't have an O2 sensor or a ECM. Can a clogged CAT cause a rich idle in this application?

[@ReviveAndDrive-mk1]

[@theoboyee5597]

And I noticed to that my driver side exhaust it looks like oil drops falling out of it, but not the passenger side exhaust so my theory could be a valve, but I know there’s two different valves, exhaust valve and a manifold valve I am assuming still learning this mechanic stuff…🤦🏽‍♂️ just trying to get some answers out there🙏
