slight throttle opening = bucking
Ah-HA! I have this problem. Warm, cold, it doesn't matter. In gear in neutral, any gear really, it doesn't matter. It has been going on for 500 miles. Other than the cyclic rpms just off idle, this 1992 car runs very well. The crush mod has NOT been done.
At VERY slight throttle settings (think just off idle) the RPMs will DROP, then increase to just above idle RPM. IF you hold the throttle in this position the RPMs will up/down about 300 rpm about 1x per second. I'm pretty sure this is a TPS problem in my case. It may be a dirty intake. Other ideas?! Thanks, Stephen |

I had this problem until I loosened the gas cap.

If you take my gas pedal and say 0% is no gas, and 100% is full throttle
when its cold (and often when im driving thru town with the engine warm) about 0-25% throttle works fine.. 30%-90% there is nothing there, its like 30% all the way thru.... then it picks up from 90%-100% so I have like this huge dead space ... I have had the TPS checked.. and it checks fine... it get aggrivating.. cuz you need to speed up in town, and its either all or nothing... its like the engine just bogs down.. |

and my hesitation is so bad in the morning/night after work
that it doesnt matter if you are giving it 10% or 100% throttle it just will only go about 10 mph... |

for anyone having hesitation problems clean ur throttle body....check spark plugs...clean the intake...fuel filter...the obvious things. I have bad hesitation in the summer months....in cold weather my SVX runs very well even with defrost on. But in the summer with the a/c or defrost on the car will hesitate and run sluggish. For many that remember my situation...i had to let the car warm up fully in the summer for it to run well for the rest of the day...not the case for cold weather though. Try explaining that one....

Hey spear...clean the throttle body and intake first and see if that makes a difference.

Re: Initial hesitation

Replace this wire and it's connectors. Use a thicker, higher grade wire and when connecting it to the chassis grind orsand down to metal for excellent ground (your car will run great when you do it like this) and I learned to put on some clear RV silicone over the connector to keep it from oxidizing. I just did this (again after 10 years) on my 1992 SVX when this 'CLICKING' no-start issue started again last year and... NO MORE embarrassing start issues. So, ignore the mechanic when they say it's a battery/starter issue. The clicking no start is most always a ground issue going on. To add: Battery drain while the car is off is commonly caused by a faulty door solenoid --. Have a mechanic disconnect this door solenoid if you experience elusive, dead batteries.
