Hmm sounds like you lost all your backpressure that your computer needs to set the incoming mix's to..o2 sensor cant work that fast if it's rushing out no muffler ..cars with comp controlled fuel systems need their back pressure :)

I have an 03 grand am GT that I bought 3 months ago, its been a great car up until a few weeks ago, it starts and runs fine but when I hard accelerate it bogs down, I cant make highway speed 110 kmh, when...


The screaming and high RPM means the transmission is downshifting as it should be.
The code 420 is for catalytic converter low efficiency bank one, which could be an exhaust restriction or a fuel problem.
The easiest way to find out if it is a restricted exhaust is to remove the exhaust system where the cat connects to the pipe from the motor and test drive it a short distance. The restriction could be in the connector pipe between the cat and the muffler, or inside the muffler. A mechanic could also use an inferred heat thermometer to check the pipe temp from the engine back to the muffler while the engine is running.

I took my 1995 Ford Aerostar to have the flexpipe, muffler, and tailpipe replaced. I shopped around, and Budget Muffler in Kent Ohio stated that they would repair the care for $160+tax. When I picked...


You are right. The engine flexes differently, but not less. The designers that put the engine sideways also put the flex pipe in the design, and the shop is just saving money. I'm a mechanical engineer, and I can tell you the stresses on the joints will be higher without the flex pipe. I can't say for sure something will crack, but it is certainly more likely.

My muffler system there is 2 or 3 emission part in the pipes from the exhaust to the muffler. can a straight pipe rplact those 3 piecies?


The only component that must stay in place to pass federal emissions is the catalytic convertor. If you are not concerned with emissions then a straight pipe will be fine. There will not be any adverse performance problems with a straight pipe. Please rate my help this helps me out , Thankyou RJ

Troubleshooting 1995 Ford Probe Problem


check airflow control valve,changed cat ?? quickest test for that is slacken exhaust manifold ,noisy but ??any blockage in exhaust system will show straight away.other problems could be fuel filter ,low fuel pressure crank sensor weak signal,i think you might find its cheaper to let dealer have look than change parts willy nilly .evan had a car doing this that some jealous neighbour had shoved a potatoe up the exhaust hence now the drop manifold down pipe part
