When Im on the highway it wont go past a certain RPM.....and it takes a long time before it shifts into a lower gear...hummm I replaced the TPS Sensor.......Car also smells really bad, and is running a little rich. ANYONE had something like this happen to them?????
CAN IT BE THat my Catalytic converter is clogged????


Please help I gota a road trip to Milwaukee next week with my girlfriend....

hahahah

 

I'd say your CAT is clogged or you have some insane arcing going on
My bet's on your CAT. As to why it got clogged im not sure.

 

YEAH. IT ALSO FEELS LIKE IT HITs like a wall at a certain rpm. Irt will go past 3k rpm's but very slowly........ and the exhaust sounds a little different..it sounds loud???????

 

sounds like a clogged cat to me.

 

TTTT

FOR THE LOVE OF GOD HELP ME OUT HERE!!..hahahahhaha

 

Unbolt the exhaust before the cat and see if that helps if it does i would get a nice custom pipe put on at a shop

 

what more help do you need? we're all saying it looks like the CAT.

 

Ok, I changed the cat and the 02 sensor...........it runs smoother, BUT It still has a high Idle and is shifting weird.......


any suggestions??

 

I dont believe you mentioned that you had a High idle before.....? you might want to be a bit more descriptive, by smoother do you mean its reving past certain rpms?

 

WELL WHEN I changed the O2 sensor and the catalytic converter the engine ran smoother...as in it was stable it didnt shake and it just ran better.........the problem is just that like at 70 mph im like at 2500 rpm, and I got 2.73 gears!!!!

Well I took the throttle body off and cleaned the IAC and now at a stoplight my rpms ar like at 600 which is good. that kinda went back to normal...but still got the 70 moh rpm problem..hummmmmm

 

check for some loose plugs and wires....

 

Does the car go above 3k rpm's now? You never stated if replacing the cat and 02's fixed that. also, you said your high idle problem is taken car of also, after you clean an IAC motor, it's best to drive it for about 4-5 miles over 40 mph so it can reset itself. A vacuum leak will also cause it.

So now the only problem I think you have is the high rpm's? Are you sure the car is shifting through all the gears? I have 2.73's in my 89 T/A, I can't remember what rpm's at 70. Next time you drive the car, pay attention to how many time's it shifts, and if it feels like the convertor is locking up.

 

I drove my car tonight, at 70 mph in 3rd gear it's 2500 rpms with 2.73's with a 255/50/16 tire.

 

You can also remove the battery cables for a few minutes to reset the PCM.

 

Surprised!!!!

No one said "optispark"

Ohh well...
