#906 of 965 Re: Dead miss on 1991 Q45 [budsq45] by elwesso Oct 26, 2006 (2:24 pm)
Replying to: budsq45 (Oct 24, 2006 6:42 am) You probably have a bad injector....   You can test the injectors for resistance and determine if theyre bad. Coil packs RARELY FAIL on the Q..   http://www.q45.org/ohminjectors.html   read that see what you can come up with. IF you like, print it out and give it to your "mechanic" and have them do that...   Unfortunate how people think the dealers always know everything about the car.

#907 of 965 Q45 Fan problems by staley Oct 26, 2006 (6:50 pm)
I have a 1995 Q45. ON my way back from a trip, the fan started making a loud whooshing noise. When I gun it, I get a sound like a belt slipping. I noticed the fan blade is cracking between the blades so I ordered that. My question is should the fan spin freely on the fan clutch because right now it is difficult to spin the fan by hand. I am thinking I may need a new fan clutch. The car is running cool and fine so I don't think the water pump is going bad. Any ideas? Thanks in advance.

Replying to: elwesso (Oct 26, 2006 2:24 pm) thank you VERY much for the tip and the link... the miss disappeared by itself... been ok for 100 miles.... must have been the injector, as oil in crankcase has gas odor.... could the injector have been clogged? or was it electrically inop?

Replying to: staley (Oct 26, 2006 6:50 pm) the belt slipping is probably because the fan clutch is stuck... Ive seen it a few times, but not terribly common....

#913 of 965 my '92 Q misfires occasionally on take off by walis Dec 19, 2006 (3:23 pm)
Hello all...does anyone know what the problem might be on my Q...it misfires on take offs and it's very slow taking off. However, when on the highway, it moves well. I've replaced all 8 plugs with some NGKs. I also cleaned the airflow meter as suggested in one of the posts here but to no avail. I've dumped injector cleaners in the gas tank twice within the last month. I only use premium gas. WHat else should I do? PLEASE HELP!
