Geo Storm quitting, dying, stalling at speed

Glenn Dyer · 10-29-2009, 11:21 AM

My Geo Storm GSi 1.8 l is stalling out every few seconds at all speeds after initial warm-up. MAP sensor is good, replaced fuel filter, O2 sensor, and module. Added extra ground wire from block to body, all with no change. With no throttle change feels like timing drops off or ignition quits and/or fuel is present then gone. Sometimes rpm oscilates 3-500 rpm with no throttle change. Can kick down to lower gear and engine wants to run up to 6K. Seems almost normal at 75-80 mph. No codes. Tried temp block of EGR. wondering about TPS. Any ideas or similar experiences?

Almost sounds like a TPS issue - is there any sort of build up in the intake?

Thanks. No build up. MAF is clean. Searching for TPS now. Do you know other vehicles that will have interchangeable parts for 1.8 L GSi?

M.T.,
Definitely the TPS. Confirmed. Know any source selling, new or used? Did response above help with interchangeability? 1993, born 8/92? Not afraid to modify.

Hi Glenn

I did locate these:

http://www.napaonline.com/MasterPage...on+Sensor+(TPS)

http://www.napaonline.com/MasterPage...on+Sensor+(TPS)

This is only a representation of what is available and I generally use NAPA as a source for info. Other stores may have the TPS and NAPA is not the only source.

Good luck,

SABL
