1993 Mustang 2.3L Trouhble(again); It's slugish at accelerating from a stop(some times falling on its face and dieing), jerks at highspeeds when trying to accelerate, and has hard starts. Any help


All the above problems were happening to my truck, and the engine light never did come on. Finally changed the O2 sensor, and it runs like new again.

Sluggish acceleration, frequent jerking and engine knock at high RPM


Sounds to me like the timing is off! it COULD be bad gas though! run that tank through, and refill, then see how it feels!

I have a 97 grand am gt with 3.1 idles fine but normal acceleration and cruise is nearly impossible. Bogs down at all speeds. Hard acceleration is fine goes good.


I had the same problem with my 89 grand am it was caused by a faulty crank position sensor. Initially it would cut out when accelerating and eventually wouldn't start at all, replaced the sensor runs great again.

I have a '97 Jeep Grand Cherokee Laredo 4.0 liter that won't idle


Check your throtle postition sensor. It monitors what postion the throtle is at and sends that info to the ecm. It will go bad and cause that problem.

97 yukon 4wd. Jerks and makes noise like its


Hi amberdawn_84

My 97 yukon did the same thing (I believe). The valve body in the transmisson wears out (design problem) and causes the transmission to shift really hard. My repair was about $500 (nondealer).
LOVE MY YUKON!
